Sounds fishy to me. Can you imagine the work involved processing 30 teams worth of FA offers? I can also guarantee that a bug of that magnitude would be a showstopper for just about every player.
If what he says was true, submitting offers to the commish would not fix the problem. It would mean that he would have to pick the offer that wins and assign the player to a team.
What happens if 8 owners make the same offer? Surely he would not be able to pick the first one submitted, as that is the supposed "problem". Is he going to type a response to 7 owners that their offer was no good? Yeah right.
How will you get feedback like, "give me more years", or, "give me more money".
