Most of Jack Hughes's records have asterisks and seem to be considered records for media hype.
Like he didn't break Matthews's single season USNTDP point record. He broke Keller's total point record - a record no one would really care about if it wasn't hyped by the media. He didn't break Kucherov's single-tournament u-18 WJC record. He broke Ovechkin's all-time u-18 WJC point record, though Ovechkin did score 23 goals in total while Hughes scored 14. Few players participate at two u-18 championships, especially CHL players very rarely have an opportunity to do so. He was outproduced by Alex Turcotte in USHL in terms of PPG despite having superior linemates. Especially Caufield I'd bring up here, at u-18s too it's no wonder that Hughes's worst game was when he was playing away from Caufield, while Turcotte had his best game playing with Caufield.
Then we might or might not want to remember Matthews's USNTDP group averaged some 4.5 goals per game while Hughes's did 5.7.
So, to me this "record-breaking"-hype is a bit odd considering how many asterisks you have to use with these records.
