Both their bodies are very similar, its only the throwing touch and mental part that might be different. Who throws harder and farther Brady or Cassel? I hope Cassel can make the throws brady make, or else, the patriots will not fully utilize the talent of moss and welker. Brady made welker and moss so much better because his play complimented welker and moss well. If cassel can do the same then this season whould be positive and the patriots should get into the playoffs.
