This is probably the most subversive pick for gatekeeper and might even beat Kongo for best gatekeeper in the UFC.
Florian has mostly lost to champions and beaten everyone else.
Normally that wouldn't mean gatekeeper status, but two things change this.
The first is that Florian recently lost to Gray Maynard in a non-title fight, showing he could lose to someone other than a champion.
The other is the sheer amount of title shots he has lost.
He has lost three different shots at the lightweight and featherweight titles.
At this point he may be the championship gatekeeper, but it still means that he loses consistently to a high level of competition.
It just happens to be the highest level of competition.
Depending on if Florian does fight again and how the rest of his career goes, he may just become the best gatekeeper the UFC has ever seen.
That might be a bittersweet thing for Florian, but it would still be impressive nonetheless.
