Unrestricted free agent defenseman Matt Grzelcyk is listed at 5 feet 10 inches tall and weighs approximately 180 pounds.

I don't think there was a defenseman drafted that was under 6 feet tall. He's not the biggest guy," Coyle said," (1:27 onwards).Coyle acknowledged Grzelcyk’s tenacity and gritty playing style but pointed out that teams, looking at past playoff successes, may prioritize larger players on the backend, which could unfairly impact Grzelcyk’s prospects."Having said that I think he plays with a tremendous amount if tenacity, and he's got sandpaper to his game. I just think team's look at what has won in the playoffs, in the past, and if you were lacking size, particularly in the backend, teams are avoiding that a little bit, which isn't fair to Matt Grzelyck," he added.Despite his small frame, Grzelcyk has carved out a successful career by leveraging his strengths, which include exceptional skating, puck-moving ability, and hockey IQ.How has Matt Grzelcyk fared in the NHL?Matt Grzelcyk was drafted 85th overall by the Boston Bruins in the 2012 NHL draft.
