Flyers-Islanders preseason thoughts: NHL defense highlights Allentown roster

Flyers vs. Islanders

We'll have to wait another day to see if the Flyers truly plan on experimenting with Claude Giroux on the wing … if we ever see it at all in a game situation.

Giroux is not playing in tonight's split-squad game against the Islanders either in Allentown or Brooklyn. Tonight's rosters are heavy of players competing for spots.

Here are a few reasons to watch tonight:

• We'll get a look at the majority of the Flyers' defense tonight in Allentown as Shayne Gostisbehere, Brandon Manning, Robert Hagg, Sam Morin and Travis Sanheim are suiting up.

Gostisbehere is a lock, and Manning is as close to a lock as you can get. He could still lose his NHL job, but it appears unlikely at this point.

There are two open spots on the blue line. Hagg and Morin came into training camp as the favorites, and they appear to have taken a stranglehold on their competition.

Many thought Sanheim would push for a job, along with Phil Myers, but neither Sanheim nor Myers have done enough in camp to make the team. Things can change, but they're behind.

What I'll be watching: Gostisbehere and Hagg will be paired together. This could be a pairing when the Flyers open their season in San Jose on Oct. 4.

• Nolan Patrick has yet to find the scoresheet in last week's rookie game and last Sunday, but the 19-year-old — his birthday was Tuesday — hasn't looked out of place.

Patrick's spot on the Flyers has yet to be secured. As in they haven't said he's on the team yet. But he's had a steady camp and looked too good to play with kids his age in the rookie game and didn't look misplaced in his first preseason game.

Tonight gives us another look at the 2017 No. 2 overall pick. For many, it will be their first glimpse at Patrick. I'd bet on him getting on the scoresheet tonight.

On Sunday, the Islanders sent out a largely veteran lineup filled with most of their star players. Patrick passed that test. Tonight in Allentown, it's a little less star-studded Isles team. Patrick will be playing with Oskar Lindblom and Nicolas Aube-Kubel.

Michal Neuvirth will be in net tonight with Leland Irving backing him up, and with the Flyers banking a lot on Neuvirth this season, it'll be worth watching.

Neuvirth has never stayed healthy throughout his career. When he has, he's largely been a solid goalie. Last season was a different story. Neuvirth had the worst save percentage among qualified goalies, and he simply wasn't good.

The Flyers moved on from Steve Mason and signed Brian Elliott this summer. It's going to be a tandem with Neuvirth and Elliott, who isn't playing tonight in either Allentown or Brooklyn. How it works is a big question mark.

What you want to see from Neuvirth tonight is a steady performance. It's his first action of the year, so there will probably be rust. But you don't want to see too much rust, and you want to see him get steadier as the game goes on.

We don't know how much he'll play tonight, whether they'll split the game with Irving. But Neuvirth is definitely a player to watch tonight.
