Matt Hardy, i can honestly say ever since he has turned heel, his promoing has been brilliant, i would never have thought he was capable of pulling off the promo he did the Smackdown after 'turning' on his brother, i can honestly see him as a world champion at some point this year, a feud between him and Jeff maybe for it, which gives me reason to believe Jeff has a slight chance of winning it at NWO or maybe even Wrestlemania leading to the Hardy feud for the title.
Just the fact he has turned heel has made Matt's charcter much more intresting and entertaining, and i think gives him potential to be World Champion in the near future
I think many see huge improvements in Matt, just by looking on the forum and seeing the amount of articles about him is quite impressive, He has really grown on me since the heel turn a few weeks back which i never thought would happen, just shows how being face can limit a character.
