Among the various roster moves the Flyers made this offseason were changes effecting the team's toughness.
Sean O'Donnell and Dan Carcillo went to Chicago via free agency, while the Flyers picked up Wayne Simmonds in the Mike Richards trade.
O'Donnell was a responsible teammate, willing and sufficient heavyweight.
Carcillo has calmed down since leading the NHL in penalty minutes during his years with the Phoenix Coyotes, but still fought 13 times this past season.
Carcillo's fight performance was lackluster during the 2010-2011 season but "Carbomb" undoubtedly possesses one of the hardest punches of any middleweight in the league.
Fortunately for the Flyers, the departure of these two players opens spots for similar replacements.
O'Donnell was the 6th defenseman on the Flyers' depth chart last season. This season, the Flyers can select from Andreas Lilja, Oscars Bartulis, Erik Gustafsson, or possibly Matt Walker.
If Walker is the selection, he would be Philadelphia's second heavyweight behind Jody Shelley.
On the offensive side, Carcillo's departure and the trade of Darroll Powe creates a void in Philadelphia's fourth line checking system. Fortunately, a wrecking ball from the AHL has been on a vicious tear with aims to make the NHL team.
Zac Rinaldo tied for the AHL lead in fighting majors this past season. When the Flyers needed additional toughness in the playoffs, Rinaldo is who they called on.
Another new addition who should contribute to the action is Maxime Talbot. As previously noted, some of Talbot's actions helped contribute to the intense rivalry between the Islanders and Penguins last season. His personality on the ice is sure to cause more trouble this year.
In a wrap-up of this offseason, the Flyers will potentially have Jody Shelley, Walker, Rinaldo and Simmonds, which is an improvement over last year's set of Shelley, O'Donnell and Carcillo.
It may not take long for something to get started this year; the Flyers play Sean Avery and the New York Rangers during the preseason.
With this fight fresh in Philadelphia's mind, a young player (like Rinaldo) attempting to prove his worth might go after Avery as means of retribution.
