Alberta’s latest NHL shuffle arrives with the announcement that former Toronto Maple Leafs coach Pat Quinn will join the Edmonton Oilers, which have enjoyed a three-season no-playoff streak. He replaces Craig MacTavish, who left the franchise in April. Quinn most recently led Canada’s world junior team to a gold medal but hasn’t held an NHL job since 2006, when he left the Leafs. Alberta’s beleaguered NHL teams are experiencing their share of shakeups of late. Last week, the Calgary Flames sent coach Mike Keenan packing after the team lost in the first round of the playoffs for the second year in a row.
