#6 Tazz

Okay, so this one might have come right out of the blue - or orange - but while Tazz' WWE run was slightly underwhelming after the ECW legend's incredible debut at Madison Square Garden, the Human Suplex Machine went on to become the voice of SmackDown.
My suggestion? Bring Tazz back with Michael Cole to commentate on a segment of the show - the ultimate nostalgia throwback.
We've heard Jim Ross and Jerry "The King" Lawler quite a few times this past year, notably in the Manhattan Center portion of Raw 25, so there's no question that WWE is happy to revert away from their current three-man booth to a two-man team for special occasions, and no-one took over the SmackDown airwaves more than Tazz and Cole.
But would Tazz return? Now known under his ECW moniker Taz, the Human Suplex Machine has transformed to Human Podcast Machine and now Human Broadcast Machine - voicing a morning drivetime sports show for CBS called Taz and The Moose, not to mention releasing his very own audio-on-demand show called The Taz Show where the ECW legend covers all things wrestling.
Tazz was actually in the building for SmackDown 900, so don't rule out an appearance at 1,000 - but the orange and black-clad star said he wasn't asked to do commentary for a match, but would have been open to the idea to add to the nostalgia.
If WWE reaches out, this really could add something special to the atmosphere of the night - even if it was just for one match.
