He's +5, +9 (MIAMI loss when no other Cavs player was a net positive other than Marion and Perkins in garbage ball), +24, +6, +21, +11 in his last 6 games. That's +76 in his last 117 minutes played.
He's played 165 minutes total with James, Shump , and TT in our defensive lineups and is +27 per 100 possessions playing with those guys. He's + 13.9 per 100 in 500+ minutes with James.
He's +17.6 per 100 in over 300 minutes played with Shump; when he's in with Shump, we make an astounding 8.7 MORE three pointers than our opponents per 100 possessions. Why? One reason is that Delly is making open threes and he's stopping others from making them. Opponents are shooting only 27% from three against him, one of the best DFG% against threes in the league. Opponents shoot 6.5% below what they normally shoot when Delly guards them. Shump holds opponents to 3.5% below average, and James and TT also hold opponents to below average shooting.
He's not perfect or ideal, but he's contributing to winning in different ways and in his set times, he's excelling in passing, making open shots, shutting down 3 point shooting, and getting rebounds. With Delly on court, we are the 3rd best defensiuve rebounding team; with him off court, we are the 18th best defensive rebounding team. He tracks down long rebounds and when he doesn't get them himself, he boxes out so others can get them. With him on court, we are the 4th best rebounding team and the 3rd best offensive rebounding team overall.
He knows his role, does some things really well, and plays every game as if it were his last. I'm glad he's here.
