And I agree with Zito, stats should definitely play a role-- perhaps you could use stats only and no ratings?
Actually, I'll tell you my opinion.... CSSL has good talent, and honestly I think its possible even if you set perimeters, there's still going to be so much talent there will be just a ton of compensatable FAs if you use both ratings and stats. Stats are a very good approach in a league like this, because there's a lot of good talent and for the most part with stats it'll all even itself out. Maybe you could make a one player exception rule, and do stats only? And then each GM could submit one player to the exception if they fit under a certain ratings-weight?
Just concerned if you use both stats & ratings, it'll take away from FA because there will be too many comp. fas and no one will want to sign anyone
