The first part was that he was traded for Brind’Amour, which angered many people (including me), and then he was at the center of burying Bill Barber. He checked himself when Hitchcock was brought in, and helped everyone buy in. He also accepted the shutdown role and got rewarded offensively when he started feeling it later in the playoffs and getting the matchups on home ice.
I think Primeau’s legend is a bit greater than people remember. Only 2 of his points in the playoffs were on the road. Of course he was great defensively the entire time, and the moments he had were absolutely huge. That playoff was one where Zhamnov and his line was great early and got hurt then Primeau took over.
