I think there are a few "senior" professionals who don't train as often as others.
Regardless, if someone comes in with an offer for Skippy, he's no different from any other player. Take the money and move on.
Managers, player and agents play these games every window and its ridiculously pointless. I have no idea who they think they are fooling with their "no way we are selling, ridiculously low offer, seeing out his contract, improved offer not enough, bench him for being unsettled, reluctantly selling, goes with our best wishes" patter.
We are all adults here. We get it. Sometimes we lose out from the game, sometimes we benefit (like with Porter or Coke).
As for Skippy - when we he left the first time there was no dip in his performance as he ran down his contract. He doesn't seem like that kind of player.
