also here is a really nice no challenges remaining edition about challengers. interviews with the guy who does commentary on ALL the challenger streams (american challengers are the best covered of all tennis in the world IMO, absolutely free, in hd, and usually streaming all day.. so it's really easy to follow the challenger tournaments here and a cool thing to stream if you have nothing else to watch), then a challenger lifer (kuznetsov), then a coach who coaches kudla and smyczek and their unique arrangements and also career choices, then the best interview , ryan harrison who just keeps it real, really like that guy
most informative interview is with the coach, the life on the tour, how he splits his time, and the choices you have to make. october + november is the US hard court challenger swing, and players have to weigh staying and racking up point considering AO direct entry, plus possibly gaining more points than having to qualify for a lot of the indoor hard european tournaments. or they could just be tired at the end of the season and stay at home, that kind of thing. very interesting aspect of tennis, especially if you're in that bubble around the top 100
