I'm going on a limb and am probably going to sound like an ass, but a -1 here. You will limit people to only coaching teams with rosters they like and will do well with. I know several people who coach teams of friends teams' who are in total shambles, with nothing to help them out. 0-16 or 2-14 will not add to their coaching %age, even if it's just to try and help someone out. Or someone who OC/DCs a team, and they don't comply with his tactics, and end up losing games. Back in season 4 or 5 I took the team with the longest losing streak in GLB (60+) and helped them turn things around, but it took a whole season to convince the owner his players sucked, they were way underleveled and he needed to start over. I know not many people help out the needy, but to those that do it will make them seem like a worse coach than they are.
