Ottawa Senators fans might’ve doubted Linus Ullmark through the first three games of this series. He was struggling to compete with Toronto Maple Leafs goaltender Anthony Stolarz, and this was becoming an all-too-familiar trend for the goaltender who failed to get the job done during his time with the Boston Bruins.

If the Senators want to complete their audacious comeback from 3-0, they're going to need a Vezina-worthy performance from Ullmark.
