I know it sounds ridiculous to say "IT struggled" when you see him put up 26 points with 7 assists and 4 rebounds, but he did have a bit of an off-day going 6-16 from the field, and something like 2-7 in the second half I believe. Maybe it's just us used to seeing him put up 30+ in his sleep and having his spectacular 4th Quarters, so it was bound to happen obviously.
But again, you look at it, and IT struggled, so who stepped up? That's right. NO ONE.
You see Portland having McCollum/Lilliard, Toronto having DeRozan/Lowry, Washington having Wall/Beal, and when one of the players struggle, the other guy steps up and helps the team.
Celtics unfortunately don't have that player still, and the closest thing they have is Bradley (Horford is a great team player but definitely not a guy who can consistently put in buckets in the 4th like IT can). Yeah, Bradley was injured, but even with him on the floor, it seemed that when IT wasn't going, no one else could truly step up (the C's did lose a lot of games in the stretch where IT was injured, only beating a trashy Magic team).
Even if you add Butler or PG13 now, what does that do? Maybe solidifies us as second best in the East and gets us into the ECF.
But this team still has trouble dealing with opposing bigs and rebounding (maybe the stats don't show it from last night's game, but from the eye test, it seemed like their bigs had an advantage on us especially in the second half). Does PG13 or Butler solve the rebounding as well (PG13 a little, but that's it).
IT obviously needs help out there, but this team has more than one hole to fill. Also, you likely have to trade a ton (BKN Picks, Bradley, etc.) to acquire any star right now like JB or PG13, so it may end up being more of a lateral move than one that gets us into legit contention.
Might be better to extend IT, develop Smart/Brown/etc., sign a FA this summer (Ibaka or Millsap), and draft with the BKN picks. Hope one of the BKN Picks can turn into a legit scorer alongside IT.
Don't worry, we'll still hear all the rumors, but Ainge would be better suited now just trying to enhance a 50-win team with a small move for someone like Nurkic, or Bogut, or Ibaka (if he could be had for relatively cheap now).
