He's a capable defender that can rebound and provide fouls. He will barely take 5 shots a game and he may be our only option to find our 4th big. Him providing Mozgov some rest alone is worth it.
Still curious about what is going on with Dalembert...
He's not a capable defender though, he's probably more of a liability if anything given his lack of foot speed, and not even being a good rim protector because of his lack of athleticism. Rebounding wise? He's 67th in the league in REB%, and lineups with Perkins compared to Steven Adams almost always have lower rebounding rates. He's a good screener, that's about all he's worth.
Being forced to play James Jones for 30 minutes with Love hurt is a real reason.
And after seeing Perkins on the floor, Blatt would probably revert right back to that, because he's no better than Brendan Haywood. I'd rather wait to see what else becomes available via buy outs, because Perkins isn't worth playing. If Kevin Love gets hurt down the line the team isn't making deep playoff run anyway. And the last time Kevin Love missed a game before this recent Chicago one, James Jones didn't play a minute. This was just a weird decision by Blatt in a game that the Cavs clearly weren't up for.
Mozgov plays 32 minutes at center, Tristan takes the other 16 at center.
Tristan plays another 16 at PF, LeBron plays 32 at PF
JR Smith plays 35 at SF, LeBron plays 8 at SF (Assuming minutes bump for playoffs), Marion gets 5
Shumpert plays 30 at SG, Delly plays 18
Kyrie plays 40 at PG, Delly plays 8
I'm talking strictly post-season here, because the regular season really doesn't matter, they can win on the road. If you're talking regular season you just lower LeBron's minutes by 5 and bump Marion. Hell, given Tristan's youth you could easily just increase his minutes as well.
And if they sign Ray Allen, they can cut minutes from Shump, Delly, and JR. It's not ideal to play this small, but it beats the hell out of trotting Perkins out there.
