I dont see how it increases and we move on from him.
If he is playing well, then we believe more in him too and moving him would make players on your current roster be like "WTF? - I thought we were trying to win and he is playing well, and we moved him?!" -- not gonna happen IMO
If he plays bad or even average, he has no value. He is an expiring at that point with a 14 mil QO - which the team that gets him would be dump to offer. So, he is an expiring and you dont get picks and/or young players for expirings.
So, you have to hope for him to play well. But then, if he does play well his asking price goes up and his asking price is always gonna be 20% higher than his actual value because of where he was drafted. It truly is a no win scenario IMO. No matter how he plays, you are left with a series of non-ideal options. Which is why I have been arguing to move on since last December. When you look at the end and work backwards there is almost no realistic scenario where it plays out well.
