http://www.thenbageek.com/players/349-nick-young he doesn't rebound the ball well
he doesn't create assists
he averaged more shots than the averge sf, but had a lower total shooting percentage than the average sf consistently in his career. (TS 51% last year)
and blk and stl wise he was average
not very good, not alot of production
Last year he made 3.7 mill, this year he want more for multiple year, his not worth it, your better of keeping your flexiblitly than to tie up any cap space for a guy who was below average in assists, rebounds and shooting percentage.
Also as witnessed by his time in washington he is not exactly a leader.
