Quote: I like the idea of having the best player to protect my qb blindside 

This is actually a point that hasn't been brought up. There isn't nearly as much of a QB blindside in today's NFL with the shotgun being so prevalent. Not only does the play develop much faster, but the QB stays pretty much parallel to the LOS until right when he throws the ball or sometimes after the play breaks down. There is no slow developing 5-7 step dropback where the QB is getting crushed from behind at the back of it.
