eh' ...I always viewed Anderson as a more nimble slimmer sized JBL.
I think in TNA, they should try and use him like a Gregory Helms Sized Version of JBL.
Basically, a Dude that can do a good job annoying fans with a microphone, should probably have a stable or at least two henchmen that help him win matches against probably 'better' more talented wrestlers (JBL had benoit/eddie/angle to defend the belt against), like throw in a couple feuds with AJ, Kurt, & Samoa Joe or whoever, cause I mean it's not like Anderson is the great khali or something, he's more than capable of putting on decent to good matches (sometimes great matches, like his cage match against Angle), could probably fine tune a couple moves and cut down on some sloppiness, maybe string together a more 'Cena like 5 moves of Doom' (keeps guys like Rock/Cena/Hogan healthy compared to guys like Mysterio/Edge/Angle).
Like that chinese dude said, practice one karate kick a 1,000 times instead of a 1,000 kick 1 time.
