There's nothing to say he isn't a good assistant but he never really had much interest in it, he resigned after two years, came back and for some reason went to Minnesota for a year then resigned again and hasn't been in the game in seven years now.
No one ever really elaborated, but he left the team because there was a difference in philosophies with DeBoer. I'm not sure what those differences were. If it revolved around Adam Larsson and his usage. Maybe it was nothing like that and Stevens wanted everyone to play more physical and take people's heads off and Pete wasn't down for it.
But he came back as soon as Pete was fired. The new regime didn't bring him back the next year when they took over, which I remember pissed some people off.
He sat out I guess the next year or took a job with NHLN, then Bruce Boudreau drove to his house (I think?) in the offseason and begged him to come work for Minnesota. He quit after one year because his family was in Jersey and he hated to be away from them and due to whatever was going on in their lives (he may have still had young children at the time) I guess them moving to Minnesota with him during hockey season out of the question. He then returned to NHLN and I guess he's still on there? They have so many different people on there that I can't keep up.
You KNOW Lou has tried to hire him with the Islanders. We can all bet on that. Whether he's turned them down because he's not interested or whether he's turned them down because Long Island is still a 2 hour drive each way through massive traffic from his home, that's anyone's guess. If the Devils really wanted him and he really wanted to coach here, I'm sure he would, because we're probably as close to his house as the studio in Secaucus is, but that's also not a full time gig and he may like only having to show up however many nights a year he has to show up there.
He was an assistant for a few years because he became a full time assistant. He just didn't travel with the team. He cited family reasons. After Larry left in 2012 he said he was ready to travel with the team and be a full time asisstant.
