He's definitely available and fits more into the previous Briere model of getting distressed assets.
But it's not like this move was going to deliver the Flyers a Cup in Year 1, especially if they had to trade Tippett or Cates (or even Risto) afterwards too. Signing Giroux, a better back-up goalie, Martone from Day 1, Michkov picking up from his stronger regular season second-half and and improved fourth line is still probably a team taking a step forward. And then being buyers at the deadline. And if that's not what happens and they take a step back into the lottery, than yeah, the timeline didn't change.
The offer still sent a message, to players, agents and other teams. And if it failed they still have that extra first to play with (and maybe another in a future year if they deal Risto).
