The Philadelphia Flyers might have a problem on defense. That much was evident in Tuesday night’s 4-3 overtime loss to Connor McDavid and the Edmonton Oilers.

Flyers rookie Matvei Michkov, who scored his first two NHL goals to give Philadelphia a 2-0 lead, saw his efforts go to waste.

The 2-0 lead slowly evaporated throughout the second period, and though Bobby Brink restored the lead at 3-2 with 23 seconds left, the Flyers again ran out of steam.

It could have all been prevented with a little extra detail defensively.

Egor Zamula: C

For the second game in a row, Egor Zamula had a so-so performance.

Zamula was on the ice for Adam Henrique’s goal, which not only went through him, but started with him.

The 24-year-old defenseman failed to chip the puck in deep at Edmonton’s blueline, allowing the Oilers to easily regain possession without having to spend time chasing down the puck. Two passes later, the puck was in the back of the net past Sam Ersson.

Mattias Janmark’s pass attempt went right by Zamula in the crease and to Henrique, whose questionable backhand attempt fooled Ersson and gave the Oilers life at 2-1.

Zamula picked up an assist on Brink’s goal, but he hasn’t developed into the difference-maker he looked like he could be during training camp and the preseason yet, and it’s becoming costly.

Travis Sanheim: F

Travis Sanheim was on the ice for three of Edmonton’s four goals and took a penalty in the third period with the Flyers nursing a one-goal lead.

Overall, it was an unsightly performance for the usually dependable Sanheim.

The 28-year-old was stripped of the puck along the wall in the build up to Connor Brown’s game-tying goal in the second period and got caught puck-watching on Evan Bouchard’s game-tying goal with 3:42 left in the game.

Those are two pivotal moments in a game against a good team in which you need to come out on top. Sanheim did not, and it cost the Flyers a point in the standings.

In overtime, Sanheim took it upon himself to drive the net on Stuart Skinner and try to be the hero, and even though McDavid may have fouled him doing so, it was an unwise decision nonetheless.

Some of you may be wondering why Sanheim started in overtime against McDavid and Draisaitl in the first place, with options like Jamie Drysdale and Cam York on the bench. I don’t have that answer.

Matvei Michkov: A

Matvei Michkov continues to be the most effective player on the ice for the Philadelphia Flyers through three games.

The 19-year-old rookie sensation potted his first two career NHL goals in very different fashions, and despite that, Michkov finished the game with less than 10 minutes of even strength ice time.

As he gets more acclimated, the Flyers are going to be putting Michkov out there more than they may have previously anticipated.

He does not lack defensive instincts and does not shy away from contact.

He’s all the Flyers need in a first-line winger.

Jett Luchanko: C

Jett Luchanko played in his second career NHL game on Tuesday night and wasn’t really a factor at either end of the ice, but he played a ton of minutes.

The 18-year-old led all Flyers centers in ice time at 17 minutes, recording two shots on goal, a penalty, and six faceoff wins out of 14 attempts (42.9%).

Luchanko even played late in the game when the Flyers were both leading and tied with the Oilers, which shows how much a coach like John Tortorella trusts him so early in his career.

The problem going forward, though, will be finding out whether Luchanko should be “holding his own” in the NHL or going back to the OHL and steamrolling his competition there.
