With that said, we probably win 50 games if Crowder didn't get hurt last season and if all goes well we should do even better this season. Why break the bank for Butler if we could achieve exactly what you said (50-60 wins/good but not great) without him?
I mostly agree, which is why I've said that giving up what Chicago was probably asking for -- all three remaining BRK picks plus Crowder and Bradley / Smart -- would not have been worth it.
That said, I think that as constructed this team is probably gonna lose in the 2nd round, though I think they have a chance of earning the right to be killed by Cleveland in the ECF.
Swap out Bradley for Jimmy Butler and I think the Celts would be clearly the second best team in the conference, with a puncher's chance of beating Cleveland and getting to the Finals.
Sure, they'd almost certainly get killed there by Golden State, but the most recent Finals have reiterated the age-old lesson that once you get to the Finals, you never know what can happen to turn the tables.
