7. No Training Camps
Brock never did seem to like training camps all that much, and on top of that, right now, he's a fighter without a home, as Death Clutch is done and gone. Pat Barry and Cole Konrad, two of Lesnar's most notable training partners, are no longer active in the MMA game, which means they're unlikely to come back. Of course, Lesnar could always join another camp, but where, and how well would he fit in? He's used to pretty much running the show, and in any existing camp, he would wind up being second fiddle.
