Countless Dak threads ago, I made the point that positional scarcity at the QB position isn't what it used to be. A long time ago, finding a big tall guy who could make reads and throw the ball at an NFL level was hard. A lot of the guys starting in the NFL were complete bums.
That isn't the case anymore. Personally, I think a lot of the difference in QB output is really a result of coaching and teammates. If you have a good O-line, good skill position people and a coach who is worth his salt, there are a lot of guys who can play QB and look good. The college and high school games used to be very run oriented and now they aren't. As a result, a lot more QB's are getting trained.
Dak's agent didn't really get that. Philly, LA and others screwed up with their contracts. Dak's agent wanted Dallas to screw up even worse and was counting on Jerry's propensity to cave.
Now, Jerry is going to get to watch Dak go head to head with Dalton making $7m. He is going to do the math in his head and figure out how many pro-bowlers at other positions he could afford between $35m and $7m.
Dak is going to have to destroy Dalton in camp and I'm guessing he won't.
