Center Nolan Patrick, 19, the No. 2 overall selection in the June draft, is making steady progress as he tries to earn a roster spot with the Flyers.
We pose five questions about the coming season.
Flyers' goalies Michael Neuvirth and Brian Elliott have been sharp in camp, and they will get a chance to play a full game in the next two preseason contests.
If the preseason slashing and faceoff calls carry into the NHL's regular season, special teams will have heightened importance.
Giroux, one of the NHL's highest-scoring centers the last seven seasons, will make his debut at left wing on Monday.
The Flyers have 27 healthy players left in training camp, and they plan to carry 23 for the Oct. 4 opener in San Jose.
Defenseman Ivan Provorov and winger Travis Konecny, both selected in the first round of the 2015 draft, have unlimited potential and should build on their strong rookie seasons with the Flyers.
Travis Sanheim is battling Robert Hagg and Sam Morin for the Flyers' two open defensive spots.
They went 0 for 9 on the power play and slipped to 1-1-2 in the preseason.
The Flyers now have 35 healthy players in camp; they will start the season with 22 or 23.
The Flyers will have their marquee veterans in the lineup for Thursday's exhibition in Boston, but they will also have six rookies, including Taylor Leier.
He will be hard-pressed to make the Flyers' roster, but the speedy left winger made a strong case for himself Wednesday.
Right winger Nicolas Aube-Kubel went through growing pains in the AHL last season, but Flyers GM Ron Hextall believes he will have a breakout campaign.
The defenseman had a procedure on his back in late April. He hopes to be at 100 percent by opening night.
