Do people forget the contract that A.J. Burnett got from Toronto after the 2005 season? Sure, he was coming off a season in which he threw over 200 innings, but he has as much of an injury history as prior, if not moreso. And if I'm not mistaken, Burnett's injuries weren't the fluke "collided with a baserunner" or "got hit by a line drive off the pitching elbow" type of injuries. If Prior was a free agent, I don't doubt that he would have been offered a nice multi-year deal, contingent on passing a physical. If he doesn't pass, they withdraw the offer. But his injury history isn't going to limit the initial offers to one-year deals. That's simply not true: http://sports.espn.go.com/mlb/players/profile?statsId=6393
