The main event scene in ECW sucks. Plain and simple. They need to introduce new faces and get rid of the originals (except RVD/Sabu) after WM.
I would have Nick Dinsmore ditch his 'Eugene' gimmick and revert back to his gimmick in OVW, maybe even reforming his tandem with Conway. That would be instant success, imo.
Also, Monty Brown (aka Corvon or whatever) and Burke need to be pushed as top heels, especially Brown. Then, forget all this crap with Punk and push him as the (second) top face, behind Lashley. Then use RVD for name recognition, with the occasional Sabu bump and you're all set. Also, Kevin Thorne needs to slowly be built up as a top heel. He is a star for ECW. There is also the option of bringing in Benoit after WM. He would be the provide who could bring name recognition and carry the ECW roster's young guys to top matches. It isn't rocket science.
Faces:
Lashley, Chris Benoit, CM Punk, RVD - Sabu
Heels:
CorVon, Burke, Dinsmore, Thorn, Snitsky - Holly
