From what Sutter said post practice today ,it's tied to shootouts at practice. But his answer doesn't make any sense. Lewis is not a goal scorer and practice isn't the same as a game vs Ryan Miller. Your success is higher with a player who is a goal scorer esp vs an elite goalie.
On the decision to use Trevor Lewis in the shootout:
We’ve liked him in practice shootouts the last little bit, and quite honest, nobody else has taken one this year. Mike, Jeff and Kopi are the only guys. [Reporter: Is that often something that’s used quite a bit – a hot hand in practice?] Not so much. What we’ve done is work it into parts of our practices where there’s eight or nine guys that take ‘em, and depending who the goalie is, Lewie’s move last night was just part of his move.
He also said this, which really didn't make sense
On what he liked about Tuesday’s shootout loss:
We had a good chance to win. We score a second goal, we do win. [Reporter: To make it two-nothing?] Yeah.
