Lack was picked apart for five goals on just 23 shots in Thursday's 6-3 loss to Buffalo. Having a game like that against the Sabres, of all teams, is nigh unforgivable. Lack was coming off consecutive highly promising starts against the Isles and Bruins, which just makes this clunker that much more painful. It might just be time for the Canucks to give a shot to Jacob Markstrom, who's simply dominated at the AHL level this year, but hasn't yet gotten into a game as Lack's backup with Ryan Miller (lower body) out.
