That is a great developmental league that has a ton of alumni in the NHL today. They also produce a ton of D1 scholarship players after a year or two in that league after High School. The D1 scholarship route is well traveled and probably the biggest difference between the Canadian Junior system and this league.
Justin Abdelkader, Andrew Alberts, Keith Ballard, Jason Blake, Jared Boll, Matt Carle, John Carlson, Joe Corvo, Mark Eaton, Dan Ellis, Ruslan Fedotenko, Matt Greene, Rusty Klesla, Chad Larose, Joe Pavelski, Max Paccioretty, Toby Peterson, Teddy Purcell, Brian Rafalski, Patrick Sharp, Paul Statsny and Tomas Vanek are alums of NHL note.
It has continued to produce more and more NHL draft picks year over year. Phil Housley, Jim Johnson, Brian Rafalski and yes even Gordie Howe once played in the USHL.
Not a bad league to come to town.
