Bit of an odd Challenger this. Firstly you have the University of Virginia team - which could pretty well populate a Futures tournament by itself, though I'm not sure about Challengers level. Then you have the teenage contingent: Mmoh, Paul, Opelka, Kozlov, and Rubin. And then you have the more regular challenger players. Quite a mix. Anything could happen.
Surely thats what a challenger draw should really look like, an opportunity to see some potential stars of the future cut their teeth. A bit more appetising than a complete cohort of 24-28 year olds grinding out a living. Looking forward to some fireworks!
Liam's 1st round opponent could definitely be categorised as a "Clear and Present Danger", although is might take a film buff to follow my cryptic logic.
