Finding a goalie from the ranks of NCAA free agents is a challenge. There are a few undrafted goalies currently in the NHL, but not many.
Cam Talbot (University of Alabama-Huntsville) of the Detroit Red Wings and Charlie Lindgren (St. Cloud State University) of the Washington Capitals are established NHL goalies who never were drafted. Brandon Bussi (Western Michigan University) of the Carolina Hurricanes is off to a good start in his first NHL season after playing the previous four seasons in the minor leagues.
Scouts are making the rounds of college rinks each weekend with an eye out for goalies with NHL potential or who could provide organizational depth in the American Hockey League or ECHL.
Here, in alphabetical order, are 10 free agent goalies on the radar of NHL scouts this
