If I were coaching this team, I'd change the way the defense is set up...
I'd break up Lauzon-McAvoy. Lauzon has a team worst expected goals against, which means teams are getting their best 5on5 scoring chances when he's on the ice, despite the fact he's 5th on the team in 5on5 TOI. He's also a team worst -3. That pair has looked very hit or miss to me. They create a breakaway, then give up a breakaway... I don't think Lauzon has played poorly, but I don't see the chemistry, communication or coordination yet between these two.
Gryz - McAvoy
Gryz leads the defense in shot suppression AND shot generation. He also leads the defense in expected goals for, which means he's not just generating shots he's generating quality shots. He and Mac have great chemistry and every year they've played together they've dominated 5on5 hockey, which we need.
Zboril - Carlo
Zboril had a bad night against Pittsburgh but overall he's been one of our best defensemen. He's third in shot suppression and second in shot generation. However, when he does give up a shot it tends to be a very good scoring chance. Carlo is the opposite, he's very good at denying scoring chances. They haven't played together a lot, but when they are together they seem to tap into the best of each other; they generate chances better than any other pair and deny chances better than every other pair. Like I said, it's a small sample, but the numbers are so strong it's worth exploring.
Lauzon - Miller
I think Lauzon would benefit from playing with the calmer Miller. Miller is second on the team in shot suppression which would go a long way to helping improve Lauzon's numbers. They don't have a pure puck mover in the pair, but both of these guys can make plays and join the rush (Miller's crossbar rush against Pitts). They should be a punishing pair, and you can employ them more against heavier teams. Plus, they can start every PK with this unit intact.
