I only am a fan of extreme winners
I'll give
Nadal as an example. A guy who is willing to play through tremendous amounts of pain to lift trophies very modest human being but on the court a ruthless savage who's willing to die to win. Plenty of athletes don't give a fuk once they make the big stage and produce mediocre results. I only care about who I bet on unless it's a special player or athlete/team.
