A flat and undisciplined start by the Edmonton Oilers left coach Kris Knoblauch no choice but to turn to Plan B — as in backup goalie Calvin Pickard — a mere 20 minutes into Game 4 of their Stanley Cup Final series against Florida. With no disrespect to starter Stuart Skinner, who had little help in allowing three goals on 17 shots, it was the wakeup call the Oilers needed on Thursday night. Pickard stopped 22 of 23 shots and the Oilers overcame a 3-0 first-period deficit in a 5-4 overtime win over the Florida Panthers to even their Stanley Cup Final series at 2.
