Record:
53-29, tied for the second best record in the East alongside the Raptors.
All-Star - Horford; IT misses cut behind Irving, Wall, Lowry, Derozan, Butler
All-Defense - Horford and Bradley
All-NBA - None
No other league wide rewards, though I agree that if the Celts snag the #1 East seed and win 55+, Brad could win COTY.
Although ... if the Celts can finish with the #1 defense and Horford plays 75+ games, I could see him winning DPOY.
Trades - I doubt we see anything major. Maybe a trade for an expiring e.g. Gallo, Millsap, Ibaka.
Playoff Success:
For this I will assume no major lasting injuries and no major trades.
In that case, I would expect the Celts to make it to the second round. From there I'd expect an entertaining series against the Raptors, Pacers, Pistons, or Wizards, with the result being a bit of a toss-up.
Now, if the Celts do manage a trade for a piece like Gallo or Ibaka, I'll go ahead and predict they win in the 2nd round.
In any case, if the Celts get to the ECF, I'd expect a gentleman's sweep at the hands of the Cavs, provided Irving and Love are healthy.
