I like Hayward's game, but the fact that he couldn't stay healthy in Boston was really frustrating. So in that sense, I'm not sad to see him go, but it's a failure that Boston got nothing for him.
Now Boston is down one starter (Hayward), plus Kemba's knee is still suspect, the Cs have no legit big body now that Kanter is gone, and the bench is mostly young guys with little or no experience. Danny's got some work to do.
