I can't see them losing in round 1 barring injuries. The rest of the East is just so uninspiring after the Cavs, Raps, Celts.
These issues will matter more in round 2. But I don't know that this really changes anything.
Look to get FAs before the extensions for some of the vets on value deals kick in, cross your fingers that the (likely) 25% chance comes through, monitor the trade market as always, and scout the draft.
To me that plan is pretty much set in stone regardless of whether they win the championship or lose every game from here on out.
