You are right, and most of the rest of the posts on this thread are woefully wrong.
I don't know what all the criticism of Bushrod is about--he might be playing the most consistently of any of our lineman. The nonsense about Bushrod letting Abraham go is just that--nonsense. If that ball isn't tipped, it looks like Lance Moore scores a TD--the design of the play is to use the defenders aggression against them...and it was a great call.
A protection problem is not the same as a problem with the offensive line.
