It's unlikely many of these guys commit at their first opportunity, but here is a list of some of the top US born players that could commit as early as 3 weeks from now.
Some top American players eligible to commit 8/1 (not ordered for any reason)
1. Drew Daley D NTDP Buffalo, NY
2. Joey Cullen F NTDP Moorhead, MN
3. RJ Thompson F NTDP Eden Prairie, MN (re-classed forward)
4. Carter Morris F NTDP Anchorage, AK
5. Henry Meier F Everett WHL Woodbury, MN
6. Nash Roed F Waterloo USHL White Bear Lake, MN (late 2009)
7. Jack Queally F NTDP Milton, MA
8. Will LoSauro F NTDP Ridgewood, NJ
9. Chase Schulberger D NTDP Quakertown, PA
10. Mason Schemenauer D NTDP Minnetonka, MN
I think Thompson, Roed, Morris, and Schemenauer should be in the mix. The others are long shots based on family connection and geography.
