If you're an impending UFA and look around at the type of money paid to other guys that you know you're better than, I don't know how you can consider it greed. Players around Flip's age have to lock down that one big deal to make the bulk of the money they'll make in their lifetime. Logic and reason tell you that with the cap going down, players like Filppula can't be paid $5.5 mil per year, but experience tells you that somebody will pay that, or close to it. Crap, teams like Phoenix, Columbus, etc. need to hand out a bad contract or two just to stay over the salary floor!
Have you ever left a job voluntarily that you weren't fired from? I suspect most people have (or have considered it), and some people consider doing it on almost an annual basis. Did you feel like a greedy traitor knowing that somebody else had to take over your work and clean your mess up so you could go earn a little more money somewhere else?
And, while he has done well and is a valuable part of the team here, he has not flourished. It is not like Federov's situation; he will go on to enjoy success and hopefully get a good payday. He may blossom a bit with a change of scenery.
I appreciate all that you have done here and really enjoyed watching you play, but the time has come.
