Some of you older dudes probably remember Battle of the Network Stars.....
I think the NFL should go this route with ProBowl Players....make it NFC v AFC, and bust out some goofy competitions, with some serious cake going to the winning team.
NFC QBs v AFC QBs in a huge game of Dodge Ball.
WRs and CBs..... relay races.
Runningbacks / LBs.....obstacle cources.
Offensive/Defensive linemen...... tug of war.
They could come up with some other crap as well, I'm sure.
It would just be cool, and probably pretty funny, watching these guys compete in something off the wall, and without the risk of injury.
