as far as the dolphins "over spending"...i like how people keep saying that about the dolphins, about Wallace, yet no one is saying the seahawks overspent for Harvin. contracts are similar, but miami didn't have to give up any picks...
as far as Wheeler and Ellerbe, They are getting less than Dansby and Burnett. They are younger, faster, and the number 2 and 3 Blitzing LBer's in the NFL right now (PFF)
