Phil Davis
In his 12-fight run during the hey day of the UFC's 205-lb division, he was never finished or even knocked down. He was the only LHW to ever take Rumble Johnson to a decision. He went 9-3 in the UFC, including dropping a split decision to Ryan Bader that a majority of the MMA media thought he won, and was consistently ranked in the Top 5.
Then he had the foresight to sign with Bellator when he was still a highly ranked LHW in the UFC. He was paid more to do so, and Bellator's LHW division has since surpassed the UFC's in terms of Top 10 talent.
Davis hasn't been finished during his 11-fight run in Bellator. Like his UFC run, I can't recall him ever being knocked down in Bellator either. He has gone 9-2 in Bellator, but both of the losses are split decisions that a majority of the MMA media again thought he won. Both were against fellow Top 5 opponents: Nemkov and Bader.
He's 36 years old and approaching 25 fights in major promotions, for which he's been paid handsomely without ever being knocked down or subjecting himself to a high risk of CTE, because he is extremely talented at controlling where the fight goes. In all but 2 of those fights, he has managed to convince at least one judge (and the majority of the MMA media) that he won.
