I realize who you are talking about. I've looked at each situation but I don't see any of those teams doing anything this season. As I said in my post earlier, you can look at next season and say, there might be a market but, that means that Dak is playing for 2 million this year. It means that he could not start making more money till next season. Mean time, he misses out on a new contract this year and all the money that goes along with that. That's money he never sees again. It's not good business for Dak to simply wait till next year. It's not like he's making 20 mil now and holding out for 30 mil. He's making 2 mil this season with no new contract. He'd be throwing away a great deal of money if he didn't sign a deal this year.
So no, these are not reasonable possibilities for this season, as you suggest. These teams have already made most of their moves. It's very unlikely that they can do what you suggest before the 2020 season and as I've already explained, that means that Dak misses out on a great deal of money by waiting. You say I'm planning as if everything goes a certain way. Well, it's a hard cap so it does go a certain way, in terms of available cap. You, in turn, are acting as if that is not the case and it is. You are naming teams that have little to know room to swing a deal this year, let alone next year. And lets keep in mind that the Cowboys are not simply going to just let Dak walk away. It's likely to cost whichever team the 30 plus mil and draft picks to sign Dak because the Cowboys will tag him IMO.
