Friday Morning Fly-By: Can you believe the Flyers re-signed two centers in one day?

*...and one of those centers happened to be the team captain. Reports are that Claude Giroux has signed an eight-year, $66.2 million extension. Celebrations abound: [BSH]

*They also re-signed fourth-liner Adam Hall to a one-year deal worth $600K. No more complaining about losing faceoffs! [BSH]

*Eric is smart, so you should listen to him as he tells you how little influence defensemen have on their team's on-ice save percentage: [BSH]

*Great piece about Wayne Simmonds, his story, and his charity efforts this summer: [National Post]

*Free agency (officially) starts today at noon! We'll have updates as the Flyers do things. Because they'll probably do things, like sign a goalie. Stick around with us here on the site, and/or follow our Twitter list for Flyers updates. And for other NHL news, check with SBNation's NHL hub. As for what happened yesterday...

*Danny Briere is now officially a former Flyer, as he wrapped up a two-year, $8 million deal with the Canadiens yesterday. Habs fans seem to have mixed reactions. Here are some that are not happy: [Habs EOTP]

*The Maple Leafs bought out Mikhail Grabovski. Leafs fans seem to have generally negative reactions. Here are some that are really, really, really not happy: [Pension Plan Puppets]

*Two more former Flyers may have new homes today: Darroll Powe and Arron Asham were placed on waivers yesterday, both by the Rangers: [Blueshirt Banter]

*The big, big stunner of the day yesterday: Tyler Seguin and Rich Peverley to Dallas for Loui Eriksson and prospects. The Boston reaction: [Stanley Cup of Chowder] And the Dallas reactions, both from Defending Big D: [DBD] [DBD]

*After finishing that deal, Dallas GM Jim Nill grabbed some lunch and then reportedly traded for Shawn Horcoff: [Defending Big D]

*With the Senators not having re-signed Daniel Alfredsson just yet, is owner Eugene Melnyk having some money issues? Really good work here: [Hockeybuzz]

*But in the meantime, they extended Jack Adams Award winner Paul MacLean: [SBN]

*Patrik Elias re-upped in New Jersey for three years, $16.5 million: [SBN] Devils fans are happy: [In Lou We Trust]
