Huh? its not like he hasn't started a good chunk of games this year already when val was out and put up solid stat lines. TBH personally i would look at possibly moving val in the summer and keeping Biz, it's not like with our back court val gets the kind of touches he deserves any how. Biz does everything you want your big to do, clog the lane, Grab everything play good D, and protect the rim. What more do you want? And he's 23 years old.
Move the 9 pick and Ross to land a legit starting pf and bring in a decent backup C and a 3 and D type off the bench to replace ross and your set.
