When they play together, Gravel always plays the right side. Both are left handed. Gravel shows very good versatility playing his off side. He has somewhat mastered quick, hand eye, skating movements that come with playing the right side, much like Alec Martinez. IMO, when playing the off side, it's more difficult to break out and play D in our zone, but makes for more offensive opportunity on the offensive blue line with your stick to the middle of the rink, and scooping puck off the boards and walking to the middle of the rink on your forehand. With that said, Gravel is much better at playing the right side than Forbort. However, it doesn't mean that Gravel is better than Forbort when playing the left side. In fact, he has played so much right side that left side seems almost new to him and strange. It will be interesting what combinations DS decides to go with. He could put Martinez back on the left side, but that would end the Muzzin Martinez pairing. If so, that could be a spot on the right side for Gravel. If you had to look at competition for spots, it'd be like this:
Right side
DD
AM
Trotman
Gravel
Greene
Gilbert
Left side
Muzzin
AM
Gravel
Forbort
McNabb
Scuderi
