As much as it pains me to say it, there's probably a better chance now, in all honesty.
What LooseCannon said earlier makes a lot of sense -- if Boston wants to land Love, they're going to have to put together a team that makes him close his eyes and say "yeah, I could definitely make a deep run with this team."
If Simmons is right (not something that I'll co-sign right now) and Love is traded before or on draft night, then not only is Cleveland or whomever going to have to spend all year convincing Love through their play and their front office that he should stay and sign an extension, but every team that thinks they have a shot at him is going to do the same. It's going to be the Dwightmare all over again, and that might play to our advantage as a franchise: We might not be able to offer Minnesota the most attractive trade package, but we can offer him the opportunity to be the face of a marquee franchise in the NBA (plus a metric ton of money), one that has a decent coach, a great front office, and a demonstrated willingness to build championship contenders smartly.
