Danny has not had a surgery to correct something that is hurting himself and the team for god knows what reason. He could have had this surgically repaired last offseason and been back by spring training. He could have had it at the end of April when he could have returned to full strength by the playoffs (PLAYOFFS? You're talking about PLAYOFFS??). He has not done so.
So yes, I blame him for wasting a year of his baseball career floundering around when the team needs him at full strength. To the extent he "didn't know" he needed surgery or thought he could rehab the injury, that's just his own negligence - he has a guy who plays right the hell next to him who had the same exact injury 18 months earlier.
