I don't get the fuss over his medical records. The guy had the second shoulder surgery at the end of 2013/the beginning of 2014 (I don't know the exact date, I'm just going from his wiki, lol

) and hasn't had any problems since. Plus, it's not like Ainge has passed on guys who have had injuries before, like Bradley and Sullinger (I guess that concerns about his back isn't exactly the same thing, but my point is that there was definite risk in making that selection), and Avery's shoulder problems didn't stop Danny from resigning him.
