Not under the 11 year deal. He played 0.
I don't know why it's so hard for you to accept that Howson botched this. It was a distinct possibility that Carter would be very unhappy with a trade-and that's what happened.
I don't see how you can hang that on Howson.
Howson should not be contacting another team's player before he becomes a player for that team. It would fall under tampering.
The party who did wrong was Paul Holmgren by essentially blindsiding Carter after giving him an assurance he wouldn't be traded and then not being open with Howson about the situation.
Carter should have refused to report, the Jackets lobby the league to undo the trade due to this unforeseen circumstance, and then Carter either reports to Philly or has his contract terminated. If he became a free agent, he probably gets more money since his contract extension in Philly was for a hometown discount.
Looks like Carter has learned his lesson though by threatening preemptively to retire.
