His rookie year when they sucked he sat for 4 games with a UCL injury, we don't know if it's the same injury, but now that they don't suck he obviously is going to fight to play. As everyone has said, it's part injury, Dorsey being an idiot, oline sucking and barely being able to run block, not having consistent wideouts besides Diggs. Allen at whatever strength he is at is still capable of doing things no other QB in the NFL is.
