Should i make this trade?

Do not do this trade!!! Marvin Harrision is on the decline and will not put up his usually 1000+ yds 10TDs this year. Keep Garrard, he's a solid back up. Try to trade for Jamal Lewis straight up, maybe offer Edge. If you can't push that deal, then stick with LenDale White. He'll be getting the ball when and if the Titans get to the goal line. He put up solid numbers last year, and should get the ball more this year if he stays healthy. Let the other person get a QB from waivers.
