His lack of playing time left him relatively lightly-recruited on the college scene.
Kelly went to Brown’s lacrosse camp the summer before his senior year of high school — and then-Brown head coach Lars Tiffany was impressed — but didn’t know what to make of the competition he had just faced. Still, Tiffany offered him a spot and started to get more excited as Kelly’s senior year at West Islip wore on.
West Islip lost just once that 2012 season, a 7-6 early season setback against Chaminade. They finished 21-1, holding all but one opponent to single digit goals and capped off the year with a 12-7 victory over Ithaca in the state championship game. Kelly saved over 65 percent of the shots he saw and was named an All-American.
The following year, Kelly was on the bench for Brown’s opener, a 9-7 loss to Quinnipiac. The next game, Brown went on the road to play at Massachusetts, which was coming off a win over North Carolina. The Minutemen were sitting at 3-0 and No. 5 in the polls. Tiffany made the decision to give his freshman the starting nod at a venue notorious for being difficult for the opposition to play, especially goalies.
“Just the way he walked on the field in pregame warmups, he gave confidence to everyone that we desperately needed,” Tiffany said.
Kelly made eight saves as the Bears upset the Minutemen 8-7 in overtime.
Over the next four years, Kelly kept improving under the tutelage of former Virginia star goalie Kip Turner. In Kelly’s junior year, Brown went 12-5 and reached the NCAA tournament for the first time in six years.
As a senior in 2016, Brown went on a magical run to the NCAA semifinals for just the second time in school history before falling to Maryland 15-14 in overtime. They finished the year with a school record 16 victories while Kelly earned first team All-American honors after leading the nation in save percentage (60.6). He finished his Brown career with a school record 673 saves.
As good as he was on the field, his impact off the field paid even bigger dividends for Brown.
“He was a two-time captain and we had a lot of really good leaders in the class ahead of him,” Tiffany said. “He doesn't talk a lot, but when he does, people listened, they followed and they jumped. He would challenge me in a very polite way. He has a command and presence that I haven't seen very often.”
