Raiders-Cowboys discussing prospect of joint practices

By Jerry McDonald

Chances are, the Raiders will spend a small portion of training camp in joint practices with the Dallas Cowboys in Oxnard, coach Dennis Allen said Monday.

“We’re in the process of communicating with the Cowboys,” Allen said as the Raiders convened for their second week of organized team activities. “That’s something we’re looking in to. We’ll see how it goes.”

Allen said the Raiders would be visiting the Cowboys, rather than Dallas coming to Napa.

The Raiders last held joint practices with the San Francisco in 2008 and 2009, the first year with Lane Kiffin as coach, the second under Tom Cable.

Oakland also practiced in Houston against the Texans in the days leading up to a preseason game between the two teams.

The last time the Raiders and Dallas practiced against each other was in 1997, and the two held a scrimmage in the Sun Bowl in El Paso in 1998.

The Raiders and Cowboys don’t play each other in the preseason in 2014. The Raiders likely would practice against the Cowboys before either the first preseason game Aug. 8 at Minnesota or the second preseason game at home against Detroit the following week.

    I wouldn’t know. Never been with the big’uns…

    It has everything to do with F=ma. It even could have something to do with surface area. But in terms of damage the surface area is indirectly proportional to the pressure applied which is directly proportional to the force. This is why martial artist understand it is far more deadly to strike an opponent with a single knuckle than with all 4 in a fist given the same force of application.

    I am talking the Math and Science here

  • Marios Kontopyrgos

    Truth is F=MA does play a role but it is not as simple. Here we don’t know either unless we had some sensors on DJ’s chest. To find F we have to make some crazy assumptions using the momentum. So putting things in perspective as I did below using the momentum sums it up better. Again pressure is eliminated as both the knee and baseball have the same contact area. If we would be talking about anything else it would have been different. Although getting hit by a car going 100mph is worse than a baseball due to momentum and forces so that really collapses the pressure argument

  • Rico Stifler

    Yes, he was hurt playing football, but it is an injury that is extremely rare on the football field. That is why I deem it irrelevant.

  • R8drTahoe in SF

    They had a history of injuries (therefore being injury prone) up until that point in their careers…

    *sarcasm*

  • Rico Stifler

    I agree. There is video of the hit that Hayden sustained. So their momentum can be calculated. So a reasonable conclusion can be reached, IMO.

    I was wrong in regards to the knee having a larger surface area though.

  • Marios Kontopyrgos

    Please read my comment below. So you are saying that is better to get hit by a baseball rather than a car? Pressure plays a difference only when there is not much of a difference in the force being applied. A car is much more deadlier moving at 100mph than let’s say a coin. Again things do get complicated when we are talking about a human body where different parts move at different speeds. I am not here to argue on physics with anyone. Just saying that it’s worse to get hit by a knee than a baseball

  • Rico Stifler

    Still, no idea. lol

    He said the severity of the injury was due to the knee having a larger surface area. That is flat out wrong. Now if you want to eliminate pressure from the equation fine, which eliminates the genius’ answer. Works for me.

  • Rico Stifler

    I was expecting the knee to be bigger than the baseball. I was wrong on that assumption, but I am not wrong about a knee being more devastating than a baseball.

  • marks hair

    190lb db x 6mph doesn’t = a car hitting you.

  • marks hair

    New post forever ago… you lost your arguments on this page move on..

  • Marios Kontopyrgos

    Well Rico was wrong on that argument I agree. But the statement about the baseball was as bad. As I said things get complicated. It’s easy when you are talking only about 2 points colliding. No arms or legs that energy gets dissipated to.

  • Marios Kontopyrgos

    Agreed. Still though not everyone that gets hit by a car has a vein explosion. YOu could be going 200mph, crash and get out of it unharmed while another guy going 20mph crash and die instantly. It’s more of luck or lack thereof. It’s not something you would say makes a player injury prone. DMac is an injury prone player. I mean if a guy gets cancer or to make it less extreme has a bad scar on the football field that reveals bone and the next year rolls up an ankle does this make him injury prone? I don’t believe it.

  • R8drTahoe in SF

    try (190 db x 6mph) + (190lb dv x 6mph)… plus add in the strength of both players.

    No clue what that equates to…

  • Marios Kontopyrgos

    Done below. Still I believe a car hitting you is at least 100 times worse. This doesn’t mean that hit wasn’t big

  • Return

    No I am not. Don’t get this twisted. The OP said the severity of the hit was due to the knee having a larger surface area. The only way you can bring surface area into the “equation” is through pressure. I was trowing him a lifeline and he was to ignorant to take it.

    To say its better to get hit by a baseball than a car is fatuous. F=ma. You have to define the mass and accleration of each and what you mean by better. Is it better to get hit in a head by a fast ball or a magnum slug fired from from close range even though the bullett has so much less mass? A pitcher fastball flying at a hundred miles an hour can do more damage to your head than a Mack truck traveling at .00000000000001 miles an hour.

    You make a lot of unfounded statements do the math.
    P=F/A
    F=ma
    a=v/t=r/tt
    v=r/t
    A=rr

    There. You have all the algebra necessary. Note the larger the area A the smaller the P.

    Where did get me saying something about a baseball?

  • Marios Kontopyrgos

    Not saying it was you. I’m just saying that someone commented on being hit by a baseball.

  • Return

    Yeah. You are wrong.

    And the sad thing is you don’t know how to do the math and nobody can tell you different. That’s why it’s so hilarious to see you try and debate. As the physicists would say you are so wrong you aren’t even wrong.

  • Return

    Ok. Got you. I think we are pretty much on the same page.

  • Marios Kontopyrgos

    Again it has a lot to do with how the force is dissipated. Yes the Mack moving at 0.00000000001 miles will do nothing cause of pressure. BUT pressure is eliminated from the baseball vs knee conversation. That was what I was talking about. A baseball and a knee have similar contact points. YOu are right to talk about pressure in your examples given. Again I agree that the comment about the large surface area of the knee is wrong. The only thing I commented about pressure was what I wrote above.

  • Marios Kontopyrgos

    Also what I said was: “Pressure plays a difference only when there is not much of a difference in the force being applied.” A Mack moving 0000000000.1 miles will not produce a large force as the acceleration would be really small and therefore insignificant. I was not talking about momentum. Again we agree it’s just that the internet sometimes confuses people and their arguments.

    Actually this has good applicagtion. g, the accleration due to gravity is constant for both the skinny man and fat woman. Woman on top won’t hurt as much because she has more surface area and her force per area is smaller because her force is spread over a larger area. But she will tend to suffocate the skinny guy more due to greater weight, i.e. her fattness times g.

    If the guy is on top, she has much less chance of being suffocated because he has skinny times g which is way less than her fattness times g, but his sharp little ribs and elbows dig into her with a greater pressure F/A.

    Bottom line if the skinny guy is into autoerotic asphyxiation he should get on the bottom.
