In an interesting twist, its being reported that Adrian Peterson reinjured his collarbone in January, and that the lingering injury COULD require another surgery. Sounds like best case is that he misses offseason workouts and makes it back in time for preseason, and in a less rosy scenario he misses some of preseason too.
In my eyes, this should take him off the table. Beyond the fact that this is one more blow against his health report, the fact that he would miss so much of training camp would automatically mean that he's missing out. I don't understand why rookies missing one or two weeks of training camp is a big deal, but Crennel insists that it puts a damper on their entire rookie season.
