I believe the Titans offseason is to blame for their 0-4 start.
The Titans went into the offseason in great shape. They had plenty of cap room to make a splash in free agency and already had an existing roster that had just gone 13-3. They did lose Albert Haynesworth and Chris Carr. This should have been an offseason that the Titans spent a little money and built themselves for a deep playoff run in 2009. They did not. They signed Jovan Haye and Nate Washington and little else.
There were several mid-level free agents that the Titans could have signed and did not. The Titans should have picked up a solid backup CB with starting experience, but they did not. The Titans were contempt to start the year with 2 returning starters and 2 rookie backups. They should have also signed a solid 3rd safety, but did not. They began the year with 2 returning starters, the nickelback and a special teams player. Now the secondary is in shambles because of injuries and the Titans have only rookies and practice squad players to turn to.
The Titans had the money to also sign a big name player. An "icing" player if you will. Not necessarily a player the Titans needed but a player that would make the Titans better. The Giants added LB Micheal Boley and DT Chris Canty to an already stellar defense. Those are examples of "icing" players. They definitley could have signed one of the many top of the line free agent CBs and moved Nick Harper to the bench. Bryant McFadden, Leigh Bodden and Dominique Foxworth are all good corners and all changed teams this past offseason. C/G Jason Brown could have been another option. He could have started at Left Guard and then taken over for Kevin Mawae next year. He is a Pro Bowl caliber player and he is young.
The worst mistake of all this offseason was not replacing Chris Carr. Let's back up a second. We could have kept Chris Carr. He left because he was not going to be given and opportunity to move up the depth chart. Why couldn't the Titans have had an open battle for the nickelback position and let the best man win. Carr only wanted an opportunity and then we would have had one more piece to the secondary and our solid return man. But Carr did leave and the Titans did not replace him. The Titans took Carr for granted. The Titans had return man issues for years before Carr came along and they just let him walk. They should have done everything in their power to keep Carr or replace him. But their stubborness got in the way.
That same stubborness is the reason they had a weak offseason. And now they are paying for it.
