MAVS NEWS:

Brad Townsend had an article in the DMN.  He was guessing a starting lineup change may be coming.  He didn't think it would be Kleber or Exum due to concerns with their injury history.  He speculated that it could be Gafford for Lively.  Thoughts on that?

I would find this as yet another strange move. Gafford was mostly (much) worse on defense than Lively. The only change that could make sense would be either Exum or DJJ for Green, who is having biggest problems defending PnR. 

Imho, changing defensive schemes would be what would make most sense, though. Especially PnR defense. Mavs get absolutely cooked in PnR and it has very little to do with Luka or Kyrie being bad defensive players.
