Ryan Callahan is only 10 games into his tenure as captain of the New York Rangers, and nothing spells leadership more than two goals and an assist in the long-awaited first home win of the season. Doing it against the NHL's hottest team makes it even better. Callahan scored twice in the Rangers' three-goal second period, shortly after New York let a two-goal lead evaporate, and carried his club to a 5-2 victory over the Sharks on Monday night that snapped San Jose's five-game winning streak.
