Billy, Those are all very good points. I think I described the details pretty well in the thread, so there was no jumping to conclusions here.
This is a work league where we do trust each other. But having said that, I still protested the move because it was unfair. What concerns me the most is that it was done without any notification to the league (or me the opponent). If I had not been following my match-up closely on Thanksgiving (not everyone does) I would not have known to protest the move and it very well could have stood without anyone knowing. I don't care if I'm playing in a league with preachers or my wife and kids, there is no excuse for allowing this substitution after kickoff, period. I expect the commissioner to notify the entire league if an adjustment like this is made to a lineup to ensure there is no foul play.
