We do need a younger 3 who can be a starter but JJ despite his faults is the best player that we have at this position. Boki should be getting some minutes but he can't cover for JJ's mistakes and neither can Bowen.
JVG have to give boki a chance to play and get some PT under his belt...if u look at dirk and peja they didnt get significant minutes right away...heck peja didnt play a game till 2 yrs after he got drafted but when he did get PT he avg. 20 min a game in his first season in the nba... boki hasnt been given a chance....lets see what he can do if he is given a good amt of minutes and not be on a short leash..
