Strikeforce's Tim Kennedy upset Michael Bisping beat Jason Miller and made so much money doing it

It seems that fans aren't the only ones astounded by the paycheck that Michael Bisping earned this past weekend (Dec. 3, 2011) at The Ultimate Fighter (TUF) 14 Finale for his $425,000 beatdown of Jason Miller.

According to his official Twitter account, fellow middleweight and current Strikeforce contender Tim Kennedy is upset that "The Count" earned so much cheddar this past weekend at The Palms in Las Vegas, Nevada.

Check out his reaction:

#ICanAdmit that I was disappointed that @Bisping won. I'm equally disappointed that he made $425k.

Bisping hauled in nearly a half-million by soundly defeating "Mayhem" in the third round in the battle of TUF 14 coaches, which was scheduled for five rounds. Miller, meanwhile, who gassed terribly after turning in a decent performance in the opening frame, took home $45,000 in defeat.

So why is Kennedy upset?

Perhaps the fact that during his 2.5 year tenure with Strikeforce, in which he won five of six fights, he has been unable to collectively stockpile what the Briton earned in less than 15 minutes worth of work, may have something to do with it.

Lets take a look at Kennedy's recent reported numbers:

June 19, 2009 -- Strikeforce Challengers: "Villasenor vs. Cyborg - $20,000
Sept. 25, 2009 -- Strikeforce: "Kennedy vs. Cummings" - $30,000
June 16, 2010 -- Strikeforce: "Los Angeles" - $30,000
March 5, 2011 -- Strikeforce: "Feijao vs. Henderson" - $50,000

Total: $130,000

It's important to note that Kennedy -- who has admitted publicly that he hates Bisping because he cheats -- has had two additional paydays during that span, including a championship title fight loss to Ronaldo Souza on Aug. 21, 2010. at Strikeforce: "Houston," and a victory over Robbie Lawler on July 20, 2011 at Strikeforce: "Fedor vs. Henderson."

Though his actual earnings were not reported for those two events, it's safe to say that even if Kennedy had a substantial salary increase, he would still be a several big Benjamins shy of Bisping's single TUF 14 Finale purse.

It's unclear what Kennedy's true motives could be in expressing his unhappiness with Bisping's salary. Could he be genuinely upset in comparison to his own, or is he trying to set up a potential showdown with the British brawler?

Legit beef, sour grapes or all of the above?
