Seider doesn't fight because he really doesn't need to. If he fought tkachuk in this scenario, then he would be off the ice for 5 minutes while he is one of the best PKers we have. So it really doesn't show any benefit to do so. He'll get roughing calls a lot if the refs get trigger happy.
Ras isn't a big pker for us. He saw an opportunity to get tkachuk off the ice for 5 minutes and took it. Don't fully agree with the 2 minute call on him but I guess it could go either way.
The only time Seider has truly "gotten into it" is usually around the net after the whistle and an opponent is too close to our goalie. One time, Crosby took an extra wack (seider's first year) and seider flat out punched crosby in the face and crosby started whining to the ref. If I remember correctly, seider pouted or did something to insinuate the "crybaby" crosby face.
On wednesday, seider got into it with Malkin, same situation as the one I said above. He is just very good at getting under your skin when he really isn't even trying to get under your skin (or the player he is interacting with is trying to get under his, doesn't really work). There's a difference because Tkachuk intentionally seeks out to get under players skins (both tkachuk's) and seider just does it naturally, mainly because he is just a hefty body that can show some type of intimidation.
tldr: not really lol.
