Worrying about whether Dak gets voted as the Cowboys MVP or not is premature, imho. If he plays well enough to establish himself in a better category than he is now, it'll likely be considered as the parties involved see fit. We, as fans, have little to say as to the fate of this franchise. The sooner we come to realize as much, the better. Let's allow developments to be taken into consideration, first and foremost.
Whatever comes of the next contract situation will be decided by those in power to affect the results. I'll content myself with enjoying the games ahead and take the rest in stride. Let's be content with enjoying the game of football and leave the business decisions to those responsible for it.
The OP seems paranoid in his fear of Dak being unreasonable in his demands if he should succeed in proving himself worthy of demanding riches. Let's give the process time to be resolved by those directly involved in dealing with it before getting paranoid over premature fears. The Dallas FO will negotiate with Dak and Co. as they can with no help from us as fans. It's out of our hands, thank goodness.
