pretty typical for the juniors to do well in this event - usually even better than this year it seems - quoting from the document posted top of page 18:
"Last year the USTA juniors won five of eight matches on Day 1 and two years ago, led by Jack Sock, the squad went 6-2. Also last year, the USTA had two players (Connor Farren and Alexios Halebian) win their respective round-robin pools and advance to the quarterfinals with both winning one round in the Shootout before falling in the semifinals by 10-7 scores.
Two years ago, Halebian also won his pool, as did Mitchell Frank but both were beaten in the first or quarterfinal Shootout round."
you're putting highly ranked juniors against guys that aren't highly ranked college tennis players:
- best texas player (who DB just beat) finished last year #80 ITA singles rankings
- best cal player (ben mclachlan) finished last year #35 ITA singles rankings
- no georgia player in this event was ranked end of last year in singles
- no illinois player in this event was ranked end of last year in singles
- no stanford player in this event was ranked end of last year in singles
- no harvard player in this event was ranked end of last year in singles
so, even without speculating on how much these guys care about their results in this exhibition-type event that really just seems to eat up more of their time if they get out of the round-robin (yes, one guy does get a wild card for winning it, but as you can see above with their college success, none of them are going to do much with that wild card) - even trying their hardest during the college season last year these guys aren't exactly world-beaters
