There is also a difference in how players play this season versus how they will play 2 seasons from now. He was an NBA player for a few years and played decently, and above average rebounder, average defender, and below average shooter. Sully ate his way out of the league, losing his lift and modest quickness making him below average at everything. Kelly has been a little more consistent in his time in the league, as an above average shooter, below average rebounder, and at best average defender for a stretch 5. As it is a 3 point league, he has a niche, but any degredation of talent and he will exit the league as well.
