Both. I think they go hand in hand but are battles on two separate fronts. Luke is done, done, done. Been there, done that. Over. On the other side, this team needs wing depth. Period. No escaping it. Unlikely to be found for free on the trade market or cheap on the waiver wire.
And before Vivek begs Ainge, he needs to beg the guy Ainge used carry the bags for, Larry Bird. See, Vivek had it right at the start. He went straight to Larry when he bought the team IIRC. Or that was the rumor. Bird said nah, no thanks. Well, that's a nice franchise you got there Vivek. About 2-5 percent of it might be enough to get a deal done this time.
