I thought we missed LeVert against Atlanta when we had Okoro guarding Trae Young. That was ugly. Okoro doesn't have the quicks to check a point guard like Young. He's a small forward.
According to cleaningtheglass.com, the Cavs are +22 in LeVert's 31 minutes at point guard, +12.8 in his 330 minutes at shooting guard, and -3.4 in his 160 minutes at small forward.
The Cavs' most commonly used lineup of Garland, Mitchell, LeVert, Mobley, and Allen is -4.3 in 222 possessions.
I think we have a large enough sample to indicate that playing LeVert at the 3 isn't working. It might improve with time since playing the 3 is new to him, but not that much IMO.
With Dean Wade at the 3 the Cavs are +20.6 in 190 minutes. That's in the top 1% of the league.
With Okoro at the 3 we're +6.5 in 113 minutes - that's 10 points better than LeVert. With Stevens at the 3 we're -8.5.
So what to do with LeVert? He's been very good at both guard positions, but we have Garland, Mitchell, and Rubio coming back. The only thing I can think of is having DG and Don each play 32 minutes with LeVert and Rubio 16 each.
I can't see LeVert coming back next year to play 16 minutes a game. He's making almost $19 million this year. If Rubio looks good in January we could try and move LeVert to a West team that needs a guard and at least get a late first round pick out of it. But then we run the risk of an injury to DG, Mitchell, or Rubio trashing our playoff chances.
