1:50-2:10 +/- was a cheap shot by the left guard. The center was engaged with the DT, and the LG dove at his legs.
I hope that's not what our guys are learning, you can end careers doing that, and that's definitely not legal.
Been pretty clear in these two pages and few posts that I do not like that style of offense, and only brought it up because somebody mentioned the Houston Texans, which to my knowledge is Alex Gibbs current place of employment.
I highly doubt that we're going to be teaching guys specifically to go for the legs - and I agree that a player that that blocks a defender below the waist, that is currently engaged with another blocker above the waist - should be called a penalty - if a referee/umpire sees it.
I looked, and if you're talking about the inside linebacker stunt play against the Bills, the center while contacting the defender who was zero tech (head up over center) -cant' tell if it's a LB or DT that was head up on the center.....Center isn't clearly engaged with the player and has his head out on the move to get out to the second level. The LG, in Gibbs system executes his block perfectly, taking out not one, but two backside defenders, because he got the LB, as well as the zero tech.
I don't like the system, I would hope that we're not teaching it, and having reviewed a little of MIke Cummings, because I knew nothign about him before, I would highly, highly doubt that we'd be using that kind of system to teach players to block and play offense as a unit.....but if you think for a second that linemen on the field won't take an opportunity when it's available and might be necessary to send a signal to take an opponent out low, and do it legally whether it be on offense or defense.....just to give a little "hey - what's up signal...", then.....well whatever. I want players that are going to win their battles on the field.
