I am a huge Titans fan and have been since the days of the Oilers. I live 2 hours away from St. Louis and love the Cardinals. With the addition of Coach Fisher, the Rams have moved up to my #2 NFL team. I have to admit, they were waaaaaaayyyyyy back there before this (still not over Super Bowl loss). Anyway, on to Fisher.
A lot of Titans fans were sick of him and ready for him to leave. They got tired of his conservative style and tired of 8-8 seasons. I am not one of those. Even though Munchak did a nice job this year, I really miss Coach Fisher.
Be patient with him. He will not turn the team around over night. He will get the defense going well before the offense. He is conservative, but he does a great job managing games (time outs, challenges, etc.) Expect Jackson to get a lot of carries and expect Brown to kick a lot more FG's.
One thing about him is he always dominated the NFC. I think in your division he will be a great fit. I'll be pulling for the Rams at all times except when they line up against the Titans!
