These are Dak's contemporaries and we can go back and forth for eternity about who the better players are, but that's irrelevant. Are you going to put Ryan Tannehill in the same conversation as Dan Marino? Is Colin Kaepernick a peer of Joe Montana? All of these guys compare to quarterbacks who played 30 years ago if you look at volume numbers and ignore the fact that the eras are completely different. But by saying that Dak compares to all of them, you're also saying that the guys on the above list do too, which means that the comparison doesn't set Dak apart from his contemporaries and grossly skews quarterback play today in general.
Dak, as good as he is, is a fairly middle of the road contemporary quarterback in overall production, and this list doesn't even include the likes of Matt Ryan, who took a couple of years to become prolific, or Goff, Mahomes, Watson and Garoppolo who could very well surpass - by a long shot - Daks' first two years.
