I'm sure they're a nice couple of guys, but I've found every single aspect of their game to be thoroughly unremarkable. I honestly don't see them going on to accomplish much of anything of value in whatever's left of their WWE run.
A gimmick involving them intentionally packing on more weight as a means of honoring their heritage could be fun, though. I could actually see fans taking delight in them embracing letting themselves go. Like, they could get winded half-way through their battle-dance and just quit to double-fist bacon cheeseburgers instead. Fellow slobs and lard-asses would (here come the puns!) eat that shit up.
