It seemed to me that Djokovic was never a real title contender the entire USO tournament. Lost sets. Was not moving well. Faced inexperienced opposition. Not sure if I would call his loss a choke. To be honest, he should have been eliminated at the QF or SF.I admit Medvedev dominated the game, but it was quite obvious Djokovic shat himself in the dressing room, played at 60% at best and was full of emotions the entire match because of what was at stake for his legacy. He even cried while sitting on the chair. Without a doubt the biggest choke of the year imo. Anyone could have beaten him that day.
In sports there is no vulturing, because if you win, you deserve it, but I consider Medvedev's USO title an easy win after such a one-sided final.
