Though this is well intended, there really isn't any way to prove this unless a coach literally benches his best players and starts his weakest. I completely agree with Garwood:
"...Maybe they should investigate people with more than one team in the same world. To me, THAT goes against the spirit of the game, and invites cheating and throwing games."
The scouting service has become so vital in helping build winning teams that a coach must spend money to use it in order to compete in this game. But when there are 4 teams in the same world, each named Lakerhater07, Lakerhater113, Lakerhater34 and Lakerhater54 (not using anyone specific as an example) it is extremely difficult to compete against this user - obviously assuming this is the same player. With multiple teams a player can systematically recruit different regions since they have a larger bankroll. With 4 teams even at a D2 level you can nearly scout all 50 states and have money to land quality players you know will grow into special players. I've even seen players openly admit to having multiple teams in the same world and having to deal with their teams having to play each other in the post-season. Again, not calling anyone out or making assumptions that that coach would fix a game between his two teams, but it seems reasonable to suggest that a coach could fix a game between his two teams based on which team he/she feels has the best chance of surviving against the team they might play next.
This issue may be the greatest threat to the success and integrity of this game.
