If the Titans don't take my advice about acquiring Jason Taylor and Anquan Boldin, there are plenty of quality free agents to be had after this season. Here are the ones the Titans should look at targeting (in order of importance):
1. Terrell Owens Roy Williams
Owens is a free agent, but I would rather line up offensive lineman at receiver than have him on the Titans. Williams is the perfect receiver for Vince Young. The Titans should back up the Brinks truck to his door.
2. T.J. Houshmandzadeh
Williams is a better fit for VY, but getting Housh would be a huge upgrade to the Titans receiving core. If both of these guys do end up being free agents, there is really no excuse for the Titans not to get one of them.
3. Tommie Harris
I don't think I have to tell you how good a defensive line that featured Albert Haynesworth and Harris would be. Teams would have to throw on every down.
4. Julius Peppers/Will Smith
Adding either one of these guys would greatly upgrade the Titans pass rush.
Obviously the Titans will not have the cap room to add all of these guys, but if they could get 2 of them it would make them an instant Super Bowl contender. The bonus to getting these guys would be that the Titans wouldn't have to give up any draft picks.
