-- The veteran defenseman still is recovering from back surgery in May, and isn't sure if he'll be ready for training camp. Knee, foot and hand injuries limited him to 50 games and the back injury knocked him out of the Stanley Cup Playoffs. If Pronger can't play a full season at full health, all the Flyers' offseason changes might go for naught.-- He may be a 19-year-old (he'll turn 20 Aug. 22) with nine games of NHL experience, but that hasn't dimmed very high expectations. Schenn has been lauded as the best player outside the NHL, and GM Paul Holmgren compared him to Mike Richards , the All-Star center the Flyers gave up to get him.One of the players expected to pick up the scoring load this season is Simmonds. He had 16 goals two seasons ago and looked to be on the path to 20, but slumped last season with just 14. With all the subtractions the Flyers made up front, Simmonds will have the opportunity to for more ice time than he had in Los Angeles. The Flyers are hoping he can make the most out of it.
