It's all hypothetical. This player that we're referencing is relatively a nobody. He's not even someone the majority of people who read this thread would know of without looking up.
Not one single player of the top 15 or so assets in the USHL has left this year due to the new rules. A few have left due to the stupidity of the USHL in not playing young players (Reid, Kosick, Morin) and that's a real issue, but I'm still not seeing this drain of talent due to the new rules that people speak of.
Maybe it'll happen, but I don't see what this guy (a relative nobody) has to do with that point.
