I don't agree as near the end of the game when Pettine stopped blitzing Allen had time in the pocket he looked very stable, confidant and threw with zip on a few throws.
Besides, pulling a rookie QB for any reason other than he is injured could destroy that QBs confidence. Will he then be looking over his shoulder with every mistake?
We fans knew this preseason was going to be a very rough year with players on the O line that needed replacing, lousy WR corps. So many predicted 4-12 and yet are bitching anyway.
