I would find it hard to believe, rules or not, that Dak and his agent don't have at least some idea as to what his market value is worth, and what teams are interested in signing him. They aren't going to ask for the moon if no team out there is willing to pay his demand, like if Dak goes on the market asking $40 mil a year and nobody offers it, he'd, at best, look silly. And at worst he'd be put at a disadvantage in negotiating with Jerry.
Really don't see that a new contract won't get done in the offseason, but I'm not privy to the negotiations, if any....
