To me the Flyers situation, despite not immediately having a competitive roster, spells trouble.
- Leadership that's been given carte blanche to spend and win now and be extremely aggressive.
- A new coach that is known to push his superstars, which may deter some players but Johnny's responded well to historically (his dad said as much).
- A player that puts the BS aside and his interests first, as evidenced by the abrupt end to his holdout in his last contract because he 'wanted to play'.
- A team he grew up cheering for.
- Life and family circumstances that are a major draw to be back in Philly.
I think the Flyers are the only legitimate threat to luring Johnny away, for the reasons above.
