The best there is, the best there was, the best there ever will be, and a real strange run in WCW.  Originally brought in to be an enforcer for an Eric Bischoff VS Larry Zbyszko match, and then played part in a weird Montreal Screwjob rip off attempt between Sting & Hulk Hogan, the moment The Hitman was brought in to WCW, it already fell flat. From there, of all things, it wasn't until Vince Russo started booking WCW in '99/00 when Bret Hart started getting the main event push he was deserving of, but it was likely too little too late. 
While there's rumors that Bret's attitude played part in his booking, or just Eric Bischoff's interesting in all things NWO over anything else, regardless of the reason, Hart felt off in WCW.
So, with the 20/20 vision of hindsight, toss on your pink & black, pull up your armchair, and let's fantasy book what maybe could've been some of Bret's run in World Championship Wrestling.
