OTA workouts are underway for the Bills and other NFL teams.  The major focus in Orchard Park at this point is on two players that aren't taking part,  Edge rusher Joey Bosa, one of the key offseason acquisitions, suffered a calf injury and will miss the balance of the spring leading up to training camp.  Yes it's May, but it adds to the list of concerns that surround his ability, or lack thereof to stay on the field.  Running back James Cook, who wants a new contract heading into the final year of his rookie deal, as expected is not attending the voluntary portion of offseason workouts.   We'll see what happens when mandatory minicamp comes up in md-June.   Adam Benigni and Sal Maiorana join with takes on all of it and more.
