He's frozen because he hasn't managed his team all year; and with playoffs looming, if he were to begin managing his team, the already unfair advantage of certain teams having already played him (vs teams who have yet to, or teams who would only play him 1x, vs 2x) becomes very pronounced.
But more than that, with the animosity and grudge matches that have already been built; and Metro's obv connection to getting Dat_Prince to selectively do something (eg, the trades with him), the ability for Dat_Prince to "magically" set his lineup perfectly for a week when he's playing say...CoolClyde, would be ridiculous, and destroy the integrity and competitiveness of the league.
If Dat_Prince showed a shred of follow up to the league, this wouldn't be an issue; or if he just stayed totally silent, it wouldn't be an issue, either; or if he organically started to pay attention to the league, it still wouldn't be an issue and it'd just be a deal with it situation, despite the crazy advantage/disadvantage it'd present to some ppl, and that they'd get shafted.
edit -- the whole situation is stupid and unnecessary, and i don't want it to balloon even more or waste anyone's time; i didn't pay attention to anything Dat_Prince has been doing the entire season, despite ppl (naturally) complaining or having some issues with it. i guess agreed with them, personally, but i stayed silent and removed from it from a commissioner standpoint bc i'd rather have just let it be, and not get too technical about stuff and risk meddling or intefering and trying to make things "perfect".
