Tom Wilson likes to walk that very fine line, but he's also not afraid to cross it. Wilson has made a career out of operating in the grey area. Most recently with a boarding penalty on a huge hit against Cam Atkinson.
Tonight the Washington Capitals were in Toronto, to face the Maple Leafs. With the score 2-0, Wilson was going hard to the net chasing the puck and from the video it appears like he may have been bumped by Jake Muzzin. The contact caused Wilson to collide heavily with Jack Campbell, a collision Wilson didn't try hard to avoid.
