ATL was set up perfectly for the Murray trade. They had picks and a not-fully guaranteed matching contract. We wouldn't have been able to beat it even if we wanted (which I doubt we would have). Burks is no big loss. It is a gamble of course, we have to actually find something else, but I am not loosing any sleep over Alec Burks.
The Celtics are generally cautious. This off season will be no different. I think there will be moves but likely not big enough ones to satisfy all fans.
