From the June 13th issue of MICHIGAN HOCKEY MAGAZINE...
[I read MHM VERY infrequently -- it's not that interesting -- so I
can't speak to the accuracy of the info.]
 
  Since the NHL Draft began in 1969, these 10 U.S. colleges
  lead the way in producing drafted players.
 
   1. Minnesota          46
   2. Univ. of Michigan  42
      Michigan Tech      42
   4. Wisconsin          36
   5. Boston University  35
      Univ. of Denver    35
   7. Michigan State     32
   8. North Dakota       31
   9. Providence         27
      Clarkson           27

Looking at these numbers and reading the accompanying
article [which focussed on prospects Jason Botterill and Tony
Tuzzolino] gives me the impression that only players already
in school were counted.  For example, the article points out
that no CCHA player was taken in the first round in 1992.
However, Michigan's Ryan Sittler was chosen 7th overall in
1992.  At the time, Sittler was an incoming freshman.  So,
players drafted prior to entering college appear to be
missing from the above table.
