Assist are going to be critical, but I've built many 30ast/g teams that get ast by committee. So load up on those 4-6 ast/g players. Without the assist your FG% will suffer also. Here's a phenom I've seen, you draft a team with 42 boards a game and average 50 boards a game...why. Because a basketball game is going to happen regardless of what you drafted. The number of possessions are dictated by tempo not players, 180-200 shots on net total per game at uptempo. Rebounds are a function of shots on net, but ast are the wild card. In this type of league with this limited player pool, you have consider advance stat's to draft off.
