10 Fighters Who Actively Make It Hard To Be A Fan Of Them

TL;DR

Ten fighters with massive potential—including Fedor, Islam, and Hamza—who squandered fan goodwill through inactivity, division-hopping, suspensions, or erratic behavior.

Key Points

• 1.Fedor Emelianenko tops the list for never signing with the UFC despite years of negotiations. A 2007 UFC deal would have produced Fedor vs. Randy, Brock, and Cain, but M1 loyalty and failed 2016 talks left those matchups permanently on the table.
• 2.Hamza Chimaev earned his spot by being chronically inactive and shockingly boring as champion. After a dominant but dull title win over DDP, he immediately called for a 205 fight with Pereira instead of defending his belt against Shawn Strickland.
• 3.Islam Makhachev frustrated fans by abandoning two divisions without clarity. He defended lightweight gold four times, then chased 170, won it, refused to fight anyone there, and now wants back down to 155 to fight Ilia—leaving both divisions in chaos.
• 4.Francis Ngannou burned through goodwill by appearing to exploit the PFL after leaving the UFC. Despite championing fighter pay and promising to build PFL Africa, he delivered a low-selling fight, then left for a Jake Paul card against a overmatched opponent.
• 5.Nick and Nate Diaz frustrated fans with extreme inactivity during their primes. Since Nate's title fight with Henderson, he fought only 10 times across 14 years; Nick fought just five times in his 2011–2013 UFC return before suspensions and retirements derailed everything.
• 6.Chael Sonnen's repeated PED suspensions and mental collapses robbed fans of his true ceiling. He visibly didn't believe he'd beat Jon Jones, appeared to quit against Rashad Evans, and ultimately ended his career in Bellator with a demoralizing loss to Tito Ortiz.
