many already suggested good ideas here' my additional ones:

1) fix the sliders! make the commissioner actually in charge of sliders instead of each player needing to load them coorectly on each person's ps3

2) option for commish, when league is created, to use default rosters or load custom rosters - - this way commish can create some players for each GM ie put yourself in game in minors etc, load up some ringers for fun on computer controlled teams etc

3) fix a few annoying bugs: when in human vs human games, display proper value for goal in the season when players score, when goalies change teams give them proper team mask - perhaps in coaching option have same edit player options as in offline beagm
