he's a undersized big with a knack for rebounding and can shoot threes. Sullinger has the potential to be really good.
As far as Olynik I think he'll be okay. They usually don't miss with draft picks, and Olynik was their target on draft day, they were determined to walk away with him.
On draft express, they have very similar heights and Sullinger actually has a better wingspan (both pre-draft). Love has 4 more inches in a max vert, is faster, more agile and bench pressed double what Sullinger did. Sullinger isnt a bad rebounder, but Love is probably the best rebounder in the game (arguable with Dwight I suppose). Love is by far the better shooter as well, passer and has about half the fouls per game. Sullinger is shooting around 28% from 3 this year, so it may be a stretch to say he "can shoot threes" in the same vein as Love, who is shooting 38% from 3.
I guess they are
somewhat comparable, but I think they are both playing near their ceilings right now, and Love is substantially better. He's a max player, and I wouldnt give Sullinger more than 6-8 mil a year to be honest.
Ainge has a solid history with draft picks, but he has missed in the past. I don't see Olynik fitting well in a lineup with Sullinger either, nor do I ever see him being a starter on a great team.
