While Giroux and Voracek will be looking to renew their on-ice chemistry from a season ago, Giroux and Scott Hartnell will be aiming to rediscover their chemistry from two years back that made them one of the most feared combinations in the NHL.
Injuries forced Hartnell to miss 16 games last season and as a result, the 31-year-old power forward was never really able to get on track.
He managed just eight goals in 32 games and was shuffled throughout the lineup after rejoining the team at the season's midpoint. That's a far cry from the astounding 37 conversions he punched in during the 2011-12 season.
Now, in the 2013-14 campaign, Hartnell will likely begin the season back on the Flyers' top line alongside the team's dynamic centerman.
Two years ago, the 6'2", 210-pound Hartnell finished tied for sixth in the league in goals after posting the second 30-goal campaign in five seasons in Philadelphia. One of the biggest reasons for Hartnell's success (and a 13 goal increase from prior season) was, of course, Giroux.
The then-23-year-old center finished second in the NHL that season with 65 assists including helpers on 21 of Hartnell's career-best 37 goals that year.
Unlike Giroux and Voracek, Giroux and Hartnell complement one another by bringing completely different talents to the frozen surface.
Giroux is a fleet-footed playmaker who has the kind of exceptional vision that could have him pacing Philadelphia in assists every year for the next decade. He's an unselfish superstar who is just as happy setting up a teammate as he is at finishing a scoring opportunity himself.
Meanwhile, Hartnell is a bruising power forward who may not always be able to play at Giroux's pace but has a nose for the net.
The Regina, Saskatchewan native is a finisher and doesn't shy away from the tough areas to produce offense. Finally, Hartnell has outstanding hands in and around the net front to quickly deposit rebounds into the back of the opposition's goal.
If Giroux and Voracek can re-establish their chemistry from a season ago and Giroux and Hartnell can rediscover their phenomenal chemistry from two years back, the Flyers could be well on their way to an explosive offensive season.
