Why is Haslett still our DC?

[Defensewins]

Our defense fell apart at times last year. During the last preseason, before the 2010 season ever started, I knew we were not going to make the playoffs and I knew we were going to have a losing record. Because our run defense was awful.
But where I was severely disappointed in the the coaching staff and particularly in the Hasslett and his defensive staff, was I expected us to start terrible and gradually improve over the season to end the season playing half way decently. Show some gradual improvement. That did not happen. We were a roller coaster of inconsistency. Evidenced by the worst performances coming late in the season on November 15th and December 5th. The 31-7 loss to the Giants on 12/5 and the obvious 59-28 Eagles loss on 11/15 were the worst displays of defense I have ever seen. The Giants running backs were running untouched into the endzone. Hasslett is on a short leash.
