And why is that? Romo did the same. I bet you didn't complain then. Mahomes does the same every game, yet all of y'all praise him as the best QB in the game for being able to do so.
Why does Romo at all matter here? Stop the whataboutism, it's a fallacy.
Your argument is bad here. A QB getting 4,500+ passing yards is no longer some grand feat. This isn't 1983, dude. It's 2019 where we've had multiple 5,000 yard passers and had THREE of them came in a single year before. Winston has 4,000+ passing yards already as well. Should the Bucs pay him a crap load of money?
And Mahomes? Dude, stop embarrassing yourself. Mahomes had 50 TD passes to 12 INTs on 580 throws. Do you see the difference here? Not only did he have a high amount of passing yards, he had a crap load of TDs and a low amount of INTs in comparison.
When Dak has that kind of year, we'll start putting him in the conversation with Mahomes.
