I think Heatley's more well-rounded than we give him credit for.
He's shown to be a very smart back-checker, and a good defensive player. He can pull off dekes in-tight. He's a very under-rated play-maker as well. He's also, IIRC, a pretty decent guy in the face-off circle. And, obviously, he's one helluva scorer.
The only thing that really holds him up is his skating, but it hasn't stopped him from being a back-to-back 50 goal, 100+ scorer, with a great +/-.
I don't think there's a whole lot of motivation right now. The odds to make the playoffs are almost insurmountable. But a long break might be just what they need.
