Yeah fair dooze.
I wasn't suggesting you called him an asshole, but if he was full of excuses like you did suggest then that'd be pretty ass holey behaviour, from a dude who is known for some pretty shitty arrogant comments from time to time, this I don't think is one of them...
He explicitly says multiple times "not an excuse", "that's on me", quest for "greatness"(suggesting he's not great yet) .. Du Bronx was "slick", enjoyed his style etc... I just don't see this as anything but a warm post, with a generous amount of self belief, which he'd be crazy not to have as an MMA fighter, never mind the fact this is Tony we are talking about here.
You want an example of excuses go see Suga Sean.
