I think if the Celtics can actually get George and Hayward, it makes more sense for them to play George at the 2 than 4, as having a big 2/3 can compensate for Thomas' size a bit.
I could see them being more likely to trade Bradley than many expect, especially as he is an expiring and they won't have cash to resign him with George, Hayward, Thomas, and Horford.
I would love to get him for Portland, even if only for a year. He would be amazing for our guys to go against in practice, could help get the most out of Turner, has experience playing off the ball with dominant guys, and would add an incredible amount of defense for us on the permitter. Plus you could sub offense and defense with him and Dame at the end of games.
Maybe a pipe-dream, but something like this would be great for us IMO:
George and Davis to Boston (they get the rebounding they need and keep space cleared for Hayward)
Thad Young and Avery Bradley to Portland (look at the balance of this team after this deal, add a ton of vet savvy)
Crowder, Crabbe, Zeller and a Boston pick to Indiana (as good of a haul as they're gonna get for George and they get a lot of young players)
Lillard/Bradley
CJ/Bradley
Harkless/Turner
Young/Vonleh
Nurkic/Leonard
That's a hell of a 9 man rotation IMO, and that's w/o even factoring in the rookies or Aminu (who I hope to hell we get rid of)
