Roz Groenewoud hasn't been atop a podium in the last year, but we have no doubt she'll be back. The Canadian halfpipe skier has won five X Games medals over the course of her career, including gold in Aspen in 2012. A knee injury set her back during 2014's Olympic year, but just wait, with her consistency and progression of tricks, she'll be back on top soon enough.
