Theodore was honored Wednesday for being the player who best exemplifies the qualities of perseverance, sportsmanship and dedication to hockey. Tampa Bay Lightning defenseman Kurtis Foster and San Jose Sharks forward Jed Ortmeyer were the other finalists.
Theodore created a charity to benefit the neonatal intensive care unit of the hospital where his infant son died last summer.
Foster posted career bests of 71 games, 34 assists and 42 points, after returning from a broken leg.
Ortmeyer had 19 points in 76 games. He must inject a blood thinner into his stomach each day to combat a hereditary blood-clotting disorder.
