Raven was in the Marine Crops, D-Man, so yes... he is legitimately tough. Plus, all you have to do is watch his matches throughout his career to see how much punishment he could withstand.
Also, what's this bullshit I keep reading that Rocca was some kind of innovator for future high flyers of the business? GTFO with that bullshit. Anybody who knows anything about the history of this business knows that Satoru Sayama was the first true high flyer of professional wrestling. That's not an opinion, simply a fact.
So, yeah... when your best argument is that Rocco could shoot (Something that's unproven and even if it were fact, then it doesn't matter because so could Ken Shamrock, but does that mean he should beat Raven? I think not.), was an innovative high-flyer (complete BS), and that he beat legends while not naming a single one... yeah, the argument for Rocca is weak.
The fact of the matter is, Raven helped transform the business forever. ECW built their company around that character, and they thrived on it for over 2 and a half years. Raven carried that company to pay-per-view, before heading off to WCW. Moreover, Raven was really the first wrestler to wear a t-shirt and pair of jeans as an outfit to compete with in the ring, so he was innovative in that way as well.
Raven's simply had the more entertaining career, and the one that we all witnessed. Show me one Rocca match as good as Raven's matches against Dreamer, Benoit, Pillman (for anyone who thinks Raven could only work the "trash" style as some ignorantly put it, watch his match against Pillman at Beach Blast 1992), DDP, Goldberg, Rhino, Jeff Hardy, ect. Show one feud Rocca had that is anywhere near as entertaining as Raven's against Dreamer and The Sandman. You can't do it, and that's why Raven deserves to win. Bottom line.
People voting for Rocca are either strict ECW haters, or are trying to pass themselves off as if they're true historians of the business, when most likely you wouldn't know jackshit about the guy if it weren't for Wikipedia and Yotube.
