Thats what this whole thing was about, a player returning an overpayment (i.e. being available for the right price) you basically just confirmed my entire argument with the bolded. I've said 2 times, in 2 different posts that this is, in fact, not about them actively shopping Happ whatsoever, so I'm not sure why you would say that.
As for Pillar, the only value he has is defence, position players play on both sides of the ball so thats where the confusion came from. I agree he's a valuable player, however getting into his late 20's his speed is going to start to decline, and the defence will follow. I think he's got a few good years left in him, but once again for the right price I think he's pretty expendable.
