Who knows how Haley will do. But he has shown that he is aggressive as both a coach and thinker and his expectations for his players are always high. From what I've seen and read he's not afraid to push people to perform. Whether he can motivate this group (and the players he will have a say in drafting over the next few seasons) to give their best remains to be seen. But I think he's going to have the same high expectations for his coordinators, I think he will attack on both sides of the ball, and I think he'll accept nothing but the best from this team.
Hopefully he gets some FAs on the defensive line, is able to get Dorsey to grow as a player, and will run a scheme where the SS plays SS and the FS plays FS.
