Why did MMA fall off so much in Canada?
It can all be traced back to GSP's cowardly decision nearly a decade ago.
GSP vacated the belt at age 32 after he got his face beaten into hamburger meat in a split decision that essentially everyone thought he lost. He emerged from hiding to challenge a 38 year old middleweight with one eye that was never one of the top 5 active fighters in his division. Then GSP vacated again and avoided facing the division's best fighters.
The career of GSP's heir apparent, Rory MacDonald, crashed and burned, finally culminating in early retirement last summer at age 33 after repeatedly being beaten by welterweights outside of top 50.
It has been almost 10 years since TJ Grant rose up the lightweight rankings to earn a title shot at age 29, but he pulled out with an injury. Then he got concussed in training and left MMA without fighting again.
Elias Theorodou, Ryan Jimmo, and Tim Hague all died at age 34 after being cut from the UFC.
Patrick Côté and Sam Stout finished their UFC careers with losing records, each racking up 11 losses.
Mark Hominick climbed the ranks of WEC's featherweight division to get a title shot in the UFC after the acquisition, but then went 1-4 in the UFC.
Chap Laprise, Kajan Johnson, Jason Saggo were all cut from the UFC after they each lost their last 2 fights. Nordine Taleb was cut after being finished in 3 of his last 4 fights.
Mitch Clarke announced his retirement in the octagon to preempt being cut after a 3rd straight loss dropped his record to 2-5 in the UFC.
Misha Cirkunov was cut from the UFC a few months ago after losing his last 4 fights to drop his record to 6-7. He was finished in 6 of those 7 losses.
Jesse Ronson was also cut from UFC last year after going 0-5 (1 NC). His only win was overturned after he tested positive for PEDs.
Who is left?
Journeymen at risk of being cut like Tanner Boser, Marc-André Barriault (busted for PEDs), and John Makdessi.
Hakeem Dawodu appears destined for journeyman status after losing 2 of his last 3 fights and 3 of his 6 wins have come by split decision.
Kyle Nelson is somehow still in the UFC despite going 1-4-1 and being finished in 3 of those losses.
Gavin Tucker hasn't fought in over 2 years.
Charles Jourdain has talent but he has a losing record in the UFC and has lost 5 times in the last 3 years.
Aiemann Zahabi fights sporadically and now he is too old for bantamweight. Sounds like Mitch Gagnon who is even older and fights even more sporadically.
Olivier Aubin-Mercier winning a tournament in a minor league after losing his last 3 UFC fights (all on Canadian soil) is Canada's biggest MMA accomplishment in half a decade.
