2010-11: Evan Cowley skated for Ralston Valley High School in Colorado as a sophomore and played bantam AA hockey with the Arvada Hockey Association.
2011-12: Cowley played for Ralston Valley as a junior and played on the Arvada midget minor AA team in Colorado. He was selected by Wichita Falls in the third round (50th overall) of the 2012 North American Hockey League Entry Draft.
2012-13: Cowley was the top rookie goalie in the NAHL playing for Wichita Falls and was the lone player from the NAHL selected to participate in the inaugural CCM/All-American Prospects Game. Cowley was 22-24-4 and had 3 shutouts in 50 games for the Wildcats and had a 2.90 goals against and .900 save percentage. Wichita Falls missed the playoffs, finishing fifth in the South Division. Cowley stopped 15 of 17 shots he faced in the CCM/All-American game in Buffalo. He also played three games with the USA NTDP's U18 team and was 2-1 with a 2.33 goals against and .879 save percentage. In June 2013 he committed to playing college hockey at Denver. Cowley was ranked 12th amongst North American goalies in Central Scouting's final rankings and was selected by Florida in the fourth round (92nd overall) of the 2013 NHL Draft.
Cowley is an inexperienced goaltender with good height and balance. He has the proper mentality and raw skills to turn into a reliable backstop, but will need several years of development to hone his skills and refine his technique.
Cowley will join the Denver program this fall and battle with fellow Florida prospect Sam Brittain for the number one goaltending spot. It will be difficult for him as a freshman to take the job from the senior Brittain, but even as a backup should see plenty of game time for the Pioneers.
