When is the fight "clearly" lost? Silva chocked out Sonnen in the last 30 seconds of the fight. MMA is so random anything could happen. The only justified reason to tap to strikes is when you have a broken arm(OSP kick) or a knee that is severly damaged(Santos). Prolonging the fight will only result in career-ending injuries.I'd say it becomes "acceptable" (i.e., doesn't diminish the fighter) once the fight is clearly lost.
both were acceptable they only time it's not acceptable is when it's Bob SappGSP tapping to strikes wasn't acceptable......Gave up ASAP didn't sustain a beaten, showed ZERO heart....Had no family/kids at the time.
Shogun tapping to strikes was acceptable....The fight had already ended before he tapped first of all, so the tap didnt even count.....Shogun got the shit beat out of him for rounds by a known ROIDED Fighter, he still showed amazing heart, trying and trying until the end....Shogun also had kids/wife at the time....
