5 opponents for Georges St-Pierre if he chooses to return
#2 Johny Hendricks
Everyone who watched the St-Pierre vs. Hendricks fight pretty much knows that Johny should've walked away with the Welterweight Championship. In a way, it all worked out because he did eventually win the belt, but his decline since that point has been quite extraordinary.
GSP has been known to avenge his losses in the past, and this was as close as you can ever get to a screw job decision. Georges will want to prove to the world that he still has what it takes, and the potential financial reward in this rematch would be through the roof.
Plus, the odds are that it would be nothing more than a tune-up fight for GSP. Despite how good he was in the past, Hendricks is a shadow of the fighter he once was, and as a result, you'd have to imagine the bookies would favour GSP going into this one. Either way, if it comes anywhere close to replicating their first encounter we're in for a treat.
