Just a point, but one the media seems to overlook: Lavalais just BLEW up the center on that play causing li' Archie to end up on his back. He "tripped" because his line was whipped on that, and many other, plays that afternoon.
I got an autographed framed picture of Marquise Hill doing his pose over Eli when he sacked him in 2003. It is so tight. I won it at this year's Recruiting Bash. It hangs right over my bed. It's great.
i replayed it about 3 or 4 times and noticed or at least it seemed both Eli's feet were stepped on as he was backing up. I never saw it clear enough to be certain.
Without a doubt he was tripped up. The center was stepping all over him. That play is completely due to our D-line.
