We knew something was up. Nobody visits their in-laws for 13 days.

According to Frank Seravalli of the Daily News, Bill Guerin has officially signed a try out contract with the Philadelphia Flyers. He'll stick around past the end of the week and join the full team for camp, which officially kicks off on Friday. Players take the ice for the first time on Saturday.

Guerin, who turns 40 later this season, was let go by the Penguins earlier this summer when they chose not to re-sign him. He said in a TV interview with CSN Philly earlier today that he was comfortable in the Flyers organization and that he hoped something would work out.

For the record, the league minimum salary is $500,000.

Whether or not Guerin makes the Flyers once camp is over is obviously still up in the air, but as we argued back on September 1, this is not a bad thing at all. In fact, signing Guerin to a tryout contract is only a good thing.

Let's set one thing straight: there are literally no cons to bringing a guy like Guerin in on a tryout contract. Try to find one. They aren't there. He's been around, he's won the Cup, he'll push other guys hard. It'll be like having another coach in the room, except this coach can steal your job.

It should be interesting to see how this plays out, but for some of the forwards on the Flyers roster, training camp just got a whole lot more interesting.
