Well, scratch that plan. After double digit freezings over the last few weeks, my disc (with no scratches or smudges) decided to stop reading altogether. I tested all 29 of my other games, and all work fine.
The timing sucks since we were just about to get into Big Ten play, but I'm done with this game. I considered exchanging it for another copy, but after playing 40-50 games, its flaws have become very apparent. It already felt dated, like Madden 08 basically with a different coat of paint. But then I kept noticing consistent flaws in the pass defense, comeback AI, and freezing (none of which were a problem in Madden 08) so I said

it. EA is letting me exchange it for NHL 09.
I just got off the phone with FrankySox. As one of my most trusted CAG friends, I wanted to see if he'd take over. He accepted. Apparently, if I retire, he can recreate the dynasty (with all stats/records intact) by saving the dynasty file as it prompts us all to do each Monday when I update. So whenever I can get my friend to bring over his copy, I will let Franky know so he can save the current stats/results, then I'll retire and he'll remake the dynasty, and you all can continue normally.
Sorry for the inconvenience, but thanks for being good about getting games in on time. I hope the dynasty continues to be successful under the rule of Franklin Quincy Sox, Junior.
