Who knows but the gain from trading Theis doesn't look in balance to what the team might get back.
If he's gone next season so be it, but, Robert still looks like the backup center to me and Theis can play both.
He doesn't have much offense because it is his job to help the scorers score.
He gets out sized/muscled by NBA centers, but, 202 NBA games later it hasn't killed him yet.
Just don't ever seem to come out of a game saying to myself.."Theis really needed to give us more."
If Robert gets his minutes that will be great, Theis can actually sort of play the perimeter on offense sort of and hoist a three here and there and Robert doesn't do that stuff.
Hope we get a legit PF someday.
