I've got no problem with role players like Nelson, Kreider, and Trochek, each of whom is offensively skilled in his own way. Not an Abdelkader to provide "toughness" among them.
Nelson's selection in particular is being questioned, but he's the all-round, plug-and-play insurance policy in case of injury at forward that Tage is not. With a larger roster, Tage has a spot.
As fans of American hockey we should be pleased that the wealth of talent available means a player as valuable as Thompson *doesn't* make the team.
