I'm hoping that Jericho does well and last a while in this competition. Frankly, I just hope he doesn't get eliminated in the first episode like he did on Celebrity Duets. As for the rest of the cast, it looks better than the last one did. At least I like/know most of these 'stars' this time around.
I'm not sure Fort Minor qualifies as rap, but it's close enough I guess. Also, I'm pretty sure it's a "X% + Y% + Z% = 100%" kinda thing. ESPN has played it enough over the past three or four years to give me time to ponder this, sadly.
