I love Givens, he'd be a great addition.
I have no problem with Givens, but I think the market is going to set his price too high to make it worthwhile to add him. If he wants to come to Miami for a bargain...bring him on down! I'd consider him an upgrade over Booker for our #2 WR slot at this point of Booker's career, and having Booker as a #3 WR (& Welker as the #4) would be an impressive WR arsenal for Rivers (oops, did I say that out loud?) or Frerotte or Rosenfels or Cutler or Croyle or whoever.
I still say too expensive though...
