ESPN Boston's Mike Reiss believes the Patriots could be waiting until after June 1 to sign free agent TE Dustin Keller. Players signed after June 1 do not count towards the compensatory pick formula. Keller's health is in question after he tore three ligaments and dislocated his knee just last August, but he could fill the "move" tight end void on the Patriots' roster if healthy. The if healthy part is a big if. There is also a question of whether the Patriots even need a "move" option as they transition to more of a three-wide, "11" personnel offense. Either way, Keller will be at most a late-round flier in deep two tight end leagues this season.
