Shinny has done quite well for himself considering he was a listed player in the WHL. Why wasn't Tyler Johnson drafted? Usually it comes down to size. He went to the Rangers rookie camp and I'm sure he'll be in an NHL camp next year as well.
As far as how much you "hate" these two players. If the fans around the league hate them this much, then I would imagine they get under the skin of the opposition pretty well too. It's a compliment you hate them so much. They're doing their job. As far as Gallagher and Shinny go last night, he ran after Shinneman and threw punches before Shinneman thew back, it should have been a 2, 5, 10 for Gallagher and he knew he had been baited. Gotta hold your water in the playoffs boy.
