Screw King of the Mountain matches, as long as TNA do matches like this tonight at Slammiversary then they are absolutely fine.
A lot has changed since this entertaining tag bout between Beer Money and Team 3D. Bully Ray is in the best shape since, well, probably ever, and has also been an outstanding heel. Devon is doing fine as the TV champion (although I still wonder why he even has it in the first place). James Storm has become a popular babyface who's made it to the main event scene, and Bobby Roode is the current TNA World champion.
Not bad for men who were considered either too old to go solo or not good enough to be a main event player.
