Even the writer Rick Reilly, after the Sweet 16 OT loss asserted that BYU only had "Pizza delivery boys" and Jimmer. IMO, Jimmer had great players around him who subordinated their own scoring talent to Jimmer for the sake of the team. i believe Hartsock, Davies, Abouo, Emery, Colinsworth were all unrecognized high end D-1 players on that team.
And Hartsock was a good defender before his junior year and not really recognized until his senior year.
