On Allen turning to the wrong guy - I thought that play might have been on Demby as he turned outside to a man that was already blocked by Havs. Allen was locked up too. Demby was the guy not blocking anyone.
Growing pains for the coach and the QB are to be expected. They are 2 of the youngest at their realtive positions. (McCoy is THE youngest). Which is ok. You can't expect to walk through everyone all the time - you have to learn to do that. Brady and Bellicheck seem like they do it year after year, but they've been together for 20 years!
