If we end up with 8 teams I suggest you increase the roster sizes, because there's gonna be a ton of good players left if it's kept the way it is. I ran a league last year that had 8 teams and this is what my roster setup was:
C, C, C, LW, LW, LW, RW, RW, RW, D, D, D, D, Util, Util, G, G, G, BN, BN, BN, BN, BN, BN, IR, IR, IR, IR
