After tossing the eventual game-winning touchdown pass to Mike Bradwell in the fourth quarter, Zach Collaros suffered through a few nervous moments. “It was nerve-wracking, but we pulled through,” said Collaros, who threw four touchdown passes to lead the Toronto Argonauts (8-4) to a 33-27 win over the Calgary Stampeders (9-3) in front of 28,781 fans at McMahon Stadium.
