As for Simon Bucci, he hasn't impressed me since his ECW days (and I mean the "real" ECW, not McMahon's reincarnation), and with the issues he had in his trainer position, I doubt TNA will pick him up. However, I think Nick Dinsmore would be a great pick up for TNA. His ring work has always been entertaining and I always felt his "Eugene" gimmick held him back. I think, if he is pushed right and put in some decent angles, TNA can really push him to the next level.
Remember, it was about 10-12 years ago that WCW let go of Steve Austin, whom they deemed rather useless and was saddled with his "Stunning Steve" gimmick. After a year in the WWE, he completely reinvented himself and he carried the company to glory. If Dinsmore has the right motivation and is given room to develop his character, he can be a huge asset for TNA. I think it would be great to see him pop on Impact and deliver a promo denouncing his stay in the WWE and his past gimmick. It could be the boost his career needs.
