No offense to Guerin, but this shouldn't even be close.
Barasso was named a top three goalie five times spanning 15 years. He was very good in two consecutive Stanley Cup victories. He was inconsistent from year to year - but that's also true of Guerin.
Guerin placed in the top 20 in scoring once in his career, he wasn't anything special defensively, and his numbers dropped off quite a bit in the playoffs.
Barasso is a borderline Hall of Fame candidate. Guerin is a Doug Weight or Jason Arnott level player at best - he shouldn't have a single vote here.
