The correct answer is one of each.
A big that does both would be best, but, unfortunately very few, if any, bigs like that exist any more.
You mean between the 2 they have to score, rebound and defend?
We have Sully who can rebound.
Big who scores and defends...but can't rebound? That's a rare combination.
Although Sully has grown into a solid defender, I'm pretty sure what we're talking about is an anchor defensively. As a help defender he draws charges but he isn't intimidating.
Sully has scoring potential I guess.
So we need a defensive big. As many have said.
Come to think of it, weren't we half decent with Jason Collins? I think I've repressed those memories of the mess that is early-mid-season 2012-13 Celtics.
Kind of wish we got Ezeli now. I can see why Ainge jumped on Moultrie and PJIII. Still hoping for Melo.
Steve Adams? We're talking long run here.
This is looking like a krook post with all this thinking out loud.
