I did a quick screen for any players that played for both USHL and CHL within a year of their draft year. It spit out 46 guys on NHL rosters and reserves today (list below). There may be others.
From a points perspective, here are the totals
USHL 1,250 GP -- 364 g -- 543 a -- 907 pts -- 0.73 ppg
CHL 2,324 GP -- 753 g -- 1,278 a -- 2,031 pts -- 0.87 ppg
If USHL was such an inferior league, wouldn't we see their numbers generally decline when they moved to CHL?
I really only see six guys who preformed better in USHL: Boucher, Milano, Cotter, Montgomery, Pastujov, Sillinger. The rest did better in CHL.
Note: Age of USHL seasons was 0.7 years younger than age of CHL season.
