I'm gonna rate him a bit higher than others because I was a mark for dude.
-Mic work/promos
His strongest category especially post injury. His ability to talk was what really got the Loose Cannon character over, and worked everybody from the fans to the other wrestlers to even the promoters of the era. Even as a white meat baby face he wasn't a bad promo. With Pillman, nobody knew where the character stopped and Brian Pillman the guy started. 10
-Personality/gimmicks
Flyin Brian was again a good white meat baby face. He was a fantastic heel along with Stunning Steve in the Hollywood Blondes and both guys really committed to that gimmick. The Loose Cannon was revolutionary and I can't help but think of the untapped potential he had with it. He was just starting to scratch the surface of what he could be. 10
-Ring work (along with some of your favorite matches/feuds)
I enjoyed his match with Liger at SuperBrawl. He had a very good match with Luger for the US Title. Many different multiman tag matches to list, his tag match with Liger against Nikita Koloff and Steamboat, WarGames with Sid and the powerbomb, the ten man tag at Canadian Stampede. Even a good RAW match with Austin in 97.
8
-Overall rating (which doesn't have to be an average of the above scores)
His legacy will always be full of what ifs. What if he never got hurt maybe being the biggest what if, the accident is what really cut short the great matches he could have, not so much the death as weird as that might sound. He could still take part in a great match, sure...(Canadian Stampede) but not be the whole reason it was great. If the injury never happens it's possible his career and life takes a whole different trajectory. As is, the guy had a bunch of different angles and moments that hold up all these years later (Flair for the Old, Pillman's got a Gun, etc.) His legacy is largely question marks of what could be, but I highly enjoyed the work he did so I gotta say 9.
