Just offered a trade where I would get Larry Fitzgerald for Roddy White. Should I pull the trigger, or should I stand pat, or look for another deal to improve the team?

My team (10 teas, 3 keepers, non PPR)
QB Ryan, Peyton
RB Mendenhall, Benson, BJGE, Hightower, Tate, B Scott, Charles
WR White, Wayne, Manningham, Doucet, Lance Moore,
TE Vernon Davis
