No....the o-line was terrible in McNabb's last couple seasons with the team, Kolb's tenure and Vick's time as well. The bigger problem is that the entire game, Vick was getting clobbered with late hits, but not one call was made until he got hurt and on Kafka's 3 snap of the game, when Abraham gently pushes him.
If they have that rule in to protect the QB, than that should be called for all QBs, this would have never happened if the refs had laid the law down in the first qtr to make the d-players think twice before coming in late constantly and laying the wood on Vick.
The play he got concussed on quite possibly would have been worse, if he hadn't run into Herremans. Watch it, Vick throws the ball, Moore takes a step after jumping over a cut block and twists him around. If Herremens isn't there than Vick would have been slammed straight into the turf, which IS a penalty.
