Sometimes the DNA is right there to see. Eric Musselman, 53, is the basketball coach at Nevada. In 2015 he took over a program that had won 36 games in its previous three seasons and has won 81 in the three since, including two consecutive appearances in the NCAA tournament and a narrow loss to Loyola-Chicago in last year’s Sweet 16. His team is sure to be very good again this season, ranked No. 6 by Sports Illustrated. Musselman is short (5' 7") and wiry, driven and constantly in motion, as if chasing something. He became a head coach at 23 and has held 15 jobs in 30 years at every level above high school.
