It seems that quite a few players would like to see everyone play the same save, so how about three categories:
1. Freestyle - these players can reroll as often as they want, even replay their game and no restrictions are put on their play.
2. Excel - these players hold to the present rules, no rerolls but no penalties for using spreadsheets, WB save trials, etc.
3. Ironman - these players play with no rerolls, just themselves versus the AI, a la Kasparov vs. Deep Blue.
In this way, players who dont submit because they blunder or lose their way
can try again, finish and still submit a game. Also, the Freestyle players could have access to a forum thread as Ribannah suggested where they can discuss the game as they are playing it, get help and share experiences. 
If rerolling is allowed the Freestylers could score a few points for a game submission but they couldnt win an award. Eventually they would produce a game without rerolling, submit it and see their rating and ranking improve. This would be good incentive to submit a failed effort, therefore more people would submit, the GOTM staff need not worry about people cheating and we all play the same save for comparison sake.

...I also think there ought to be some kind of additional posting requirement for participating in the gauntlet though. Perhaps a certain set of data points could be required for specific dates set by the game designer ahead of time. Requiring full-fledged strategic spoilers would be nice, but I don't think it would be right to risk allowing language barriers to restrict participation in the gauntlet. Alternatively (and I think better) would be a requirement to submit specific game saves (say, 1000 BC, 1AD, and 1000 AD) by certain pre-set calendar dates. Perhaps by the 10th, 17th, and 24th of a given month, all to be unveiled to the community together a day or two later. Tightening up the playing time might restrict the field a bit, but we are talking about a "elite" -type gauntlet here and not the regular xOTM... participation ought to be fairly restricted anyway.
