The Miami Herald's "understanding" is free agent Dustin Keller may turn to the Giants or Bills after talks broke off with the Dolphins. The Dolphins only offered Keller a one-year contract. His agent has also "reached out" to the Broncos. Keller is one-dimensional in that he can stretch the seam, but lacks blocking ability and isn't an ideal mismatch creator at 6-foot-2 and 250 pounds. Rob Gronkowski is 6-foot-6. Jimmy Graham is 6-foot-7.
