You can't honestly think that. There's no way.
Brad Marchand has been suspended 6 times for 19 games, fined an additional 3 times, and is perhaps the league's most notorious punchable-faced rat. People literally refer to him as the "little ball of hate." Skinner has been suspended 1 time for 2 games back in 2012 and has never faced any other discipline. Marchand has more penalty minutes through the first 34 games of this season than Skinner has ever had in any year ever. There are 10-minute long compilations on youtube of Marchand making dirty plays; the entire first page of results (at least--I didn't go beyond that) when you search "Jeff Skinner dirty play" is sick goals he scored.
