Confessing after being caught severely reduces the legitimacy of your apology in my opinion.
Sure but what else can the guy say that this point. It's the best thing he could have said, imo. I agree with you though. Hard to give much credence to the words of a cheater after he's been caught.
It's a real shame. I have been pretty impressed with T. Silva in his UFC career. Aside from the Machida fight, he obliterated his other 5 UFC opponents. And then there was the Evans fight where he looked dangerous and nearly TKOd Evans even though he was clearly well below 100% for that fight due to his back injury.
I just think it's a shame.
