worst top 2 pick out there. Twelve years in the league. Almost 7K points. Over 2K blocks. Certainly not an NBA all-timer, but a solid player for a lot of years.
Cosic is an open question. He was drafted twice (different rules then) but opted to stay at BYU after the first time, and to go back home after the second, where he had a great career and life, so you can't blame him. Could he have had NBA success? I think so, but you never know.
