Do coaches sometimes play veteran scrubs like Tanner Glass even though a younger guy is a net positive, but may make a blatantly bad play that results in a goal against rather than a more subtle goal against where the team gives up a goal because of the veteran just generally sucking? So I feel like playing a scrub that may more subtly cost the team makes the coach look less bad than the rookie that makes a blatant mistake. So the coach may play the scrub to save his own ass rather than play the best team. Is this just me trying to rationalize why an otherwise rational coach would play Tanner Glass when he has a legit NHL player that he sits? Or is there something to this?
