If Louis isn't injured on the play, we're not even talking about this except to maybe say it was a good block to try and clear the way for the ball carrier. They were both moving sideline to sideline. I think Jared got a bit high, and if he gets fined for a hit to the head, I would be ok with that, but I don't think he intentionally went for the head area, he just laid out a good block and maybe got a bit high. I think talk of suspension is pretty ridiculous, personally.
He just jumped up because he was blocking a 7 footer!
He jumped to get the momentum necessary to have a successful block. He's giving up quite a bit of mass, he needs momentum on his side to be successful in blocking him. In the absence of leading with the crown/top of his helmet, it is legal to leave your feet to make a block. Where it become grey is that he did slide up into the head/shoulder area (hit shoulder to shoulder first), and so could be fined for that.
Their shoulders brushed on the way up, that's about it. At best, the contact starts half an inch below the facemask. At best. Also, as evidenced by the Packers (?) player that got fined or will for hitting Stafford, apparently even if you slide up it still counts as hitting the head. As for needing to jump... give me a break. If that were true then every RB blocking a LB would be jumping on every blitz pickup or lead block. But what do they do? They go low. That's how you block someone bigger than you, you go high to deliver a devastating blow*. Not to "successfully block". * - I have no problem with devastating blows. They're part of football and as I stated earlier (or maybe in the Eagles thread), they're a necessary part of the game. You make a guy worried about getting decleated and he won't go the extra effort next time. This was a cheap shot and hit someone in the head, no part of that in the game.
