6 -- The Flyers magic number, in points, to clinch the Atlantic Division following last night's win over Pittsburgh.
The Penguins can max out at 108 points should they win all five of their remaining games, and they can max out at just 41 regulation plus OT wins. The Flyers have 43 regulation plus OT wins, meaning that should the teams tie in points, the Flyers will win the tiebreaker.
Thus, the Flyers only need to reach 108 points to flat out win the Atlantic, and that's if Pittsburgh wins the rest of their games. That's six points needed in the final six games. The Flyers magic number to clinch the Eastern Conference over the Washington Capitals is eight points since that the tiebreaker isn't guaranteed.
