I don't get all excited about minors because if you let me send 62 to the plate in a game, I'm getting more playing time. So, as long as the games are played, I don't worry too much about. Although, quite frankly, it annoys some other league owners. So, to me, a commish has to say something to the worst offenders.
That said, I think the guy was trying to tell you he didn't make any moves. I believe he's saying SIMAI made the moves you were referring to. And, with that said, SIMAI was making the moves in hopes of fixing his rosters. Tell him to sign a few more minor leaguers(which I don't think he can) so SIMMY will stop making 50 moves a day.
