2012-13: Brittain had a season of fits and starts in his junior year at Denver. After wins in four of his first five starts, Brittain did not record another win for almost four months as sophomore Juho Olkinuora (Winnipeg) emerged as the Pioneers’ starter. Brittain finished the year 5-7 with a 2.95 goals against and .907 save percentage. Denver finished third in the WCHA and reached the WCHA Broadmoor Trophy championship game; receiving an at-large bid to the NCAA tournament and falling to Ferris State, 2-1, in a Midwest Regional semifinal game.
2013-14: Brittain had an outstanding season for the University of Denver in his senior season — leading the Pioneers to an NCAA tournament berth with a surprising conference playoff run — and was honored as a West first team All-American and NCHC Goalie of the Year. In 39 games for the Pioneers he was 19-14-6 with five shutouts and had a 2.22 goals against and .929 save percentage. The Pioneers finished sixth in the first-year NCHC but defeated fellow upstart Miami (which finished last in the regular season) in the conference championship game; earning an NCAA berth. Denver lost to Boston College, 6-2, in the Northeast Regional semifinals. Brittain signed a two-year entry-level contract with Florida in July 2014.
Brittain is the prototypical modern NHL goaltender with good size and a traditional butterfly style. He covers the net well and is adept at controlling rebounds. He is comfortable and calm in his crease and relies on sound positioning and fluid movements instead of the twisting, acrobatic saves. Brittain has a quick, technically solid glove hand, and moves smoothly from post to post. Injuries and inconsistent play have hampered his development, but the core attributes are all in place.
Brittain attended his first NHL training camp with the Panthers before being assigned to the ECHL's Cincinnati Cyclones at the start of the 2014-15 season. Sharing time with minor league veteran Rob Madore, who backstopped the Cyclones to the Kelly Cup finals in 2013-14, Brittain has steadily adjusted to pro hockey and has shown consistent improvement. Long-term he projects as a good minor league goaltender at worst, or an average NHL goalie if he can stabilize his play in the nets.
