Here's the assumptions for the brackets:
1) Everyone is at their current performance level. I might do a UFC GOAT bracket later, but this one is for the "current" UFC P4P Champ
2) Everyone is the same proportional size. If a guy looks small compared to his weight class, then he's small. Example: Kenny & Anderson are both fairly long & lean for their weight classes, so assume they'd be the roughly same size.
As for how much free time I have, the answer is none. I've been using this as a pressure release. I've got 5 different papers due in 3 classes over the next 5 weeks, and they're all in the 6-10 page range. Toss in work & trombone lessons & rehearsals for my upcoming concert, I've been swamped (hence my recent absence from around here).
