EHM The Blue Line

Part 1) I was thinking about playing in the USHL. My question is u know NCAA teams get there players from overage OHL, USHL etc... Just wondering does USHL just get players randomly assigned to them like FM does with youth intakes like not sure where USHL in ehm sign their players from thought i would ask before i go start my file. Because in EHM doesnt have the USHL draft

Part 2) this is kind of a Draft/League question but as far as OHL/WHL/QMJHL drafts go is there a way to say sort all of the drafted players to say which ones dont want to go CHL that way to go college route or no?

Just wondering.. I went with a full database and was wondering.. Why i get offer services for 21-30 yr olds? is this a game issue or is it because i am playing with a full database?
