Yes, I pointed this out a while ago in my Draft Predictions post. I think it would be a great move. Smackdown needs face mid-carders in order to balance out the large number of heel mid-carders they have, but R-Truth has already feuded with most, if not all the heel mid-carders on the blue brand including Shelton Benjamin, MVP and The Brian Kendrick. For a number of reasons, he needs to move to ECW to breakout more as a superstar. There is just too much talent on Smackdown right now for him to stand out.
Plus, on ECW he can get more air time and feud with guys such as Jack Swagger, Mark Henry and even somebody like Christian. I don't think he's ready to carry a show yet as I think he most likely won't be a legimate WWE main eventer in his career. But I personally think R-Truth is underrated and I also think he has great potential to be a solid mid-carder for many years to come.
His gimmick is good, he's over with the fans and he's entertaining to watch. His mic skills aren't anything to brag about though, but the guy can put on a solid match with a decent opponent. It would be a great move for him to permantely move to ECW for the time being and I think it would benefit both ECW and R-Truth himself.
