5. Shea Theodore
So you're the Canadian Olympic team and you have all the weapons you could need. McDavid, Sidney Crosby, and Steven Stamkos. With a legendary team like this, you need defensemen that can hold the fort down. Look no further than Shea Theodore.
Aside from his usual defensive duties, Theodore plays both ends of the ice well. The native of Langley, British Columbia, generates rebounds with ease and is great on special teams. Canada will have an overwhelming offense with the defenseman on board.
