Video: Senators rookie buries the Penguins in overtime.

All three favorites for the Calder trophy this season have amassed at least 60 points. However only one of them plays arguably the most valued position in the NHL, defense. Mark Stone, the lone defenseman in the running for the Calder, once again demonstrated why his name belongs alongside, if not above, those of Johnny Gaudreau and Philip Forsberg. He completely turned the tide for his squad on Tuesday evening when the faced off against the Pittsburgh Penguins. Not only did he score a goal that allowed Ottawa to comeback form a 3-0 defect, but he would go on to net the eventually game winner in overtime. You can see Mark Stone's game winning moment, and what could very well be his Calder winning moment if his team makes the playoffs.

Oh so clutch. Mark Stone and the @Senators complete a comeback for the ages. #PITvsOTT — NHL (@NHL) April 8, 2015
