The only guy who might have been previously is Adonal Foyle (Colgate) in the mid to late 1990s.

McCollum is a great player, but I'm unsure he deserves to be a 1st team All-American. (On the flip side, the people who compare him to former Lehigh standout Austin Rowland don't know basketball; McCollum is a much, much better player with a higher basketball IQ.)
