Using the VUKOTA projection system of Hockey Prospectus, Insider is taking the temperature of key players on every NHL team, continuing with the Philadelphia Flyers. For a detailed explanation of Prospectus' proprietary GVT value metric, read more here.

Note: Due to the lockout, GVT scores for the 2013 season are prorated from 48 to 82 games.

Summer Skate: Philadelphia Flyers

The Flyers suffered through a "down" season from Claude Giroux in 2013, but more devastating to their postseason chances was the fact that the team's infamous problems in goal continued. It also didn't help that their defensive corps was decimated by injuries -- the club dressed 13 different defensemen last season, tied with both of the Florida franchises for most in the league.

Unable to withstand such turmoil on the blue line, Philadelphia missed the playoffs, but the hope is that offseason addition Mark Streit will solidify the unit. Furthermore, they drafted defensemen with their first two picks. Even so, this team's fate might ultimately reside in the hands of intriguing goaltending duo Steve Mason and Ray Emery.
