For any receiver to be a factor in the redzone, the team actually has to use plays designed to throw the ball into teh endzone.
Now that Fairchild is gone, all of the WRs on the rosters become much better red zone threats than last year because Turk will hopefully throw to the end zone.
A tall WR is not the only answer.
A top flight TE is probably more of a need than a tall WR.
