It is logical if the purpose is to compare the players AS draft prospects. It does not matter if you compare different draft classes, as long as you use the same methodology and compare players from the same era. Analysts did it last year as well when they compared Darnold to Wentz, or how some said Darnold's pre-draft ratings were among the highest since Luck. Obviously, that does not mean Darnold will be as good Wentz or Luck, it is about what they did in college and potential to translate to the NFL level. Obviously, this is just for fun. It is not an exact science. This thread is about whether Sam would go #1 this year, so you cannot look at his rookie year in the NFL in order to make such a determination. You have to look at college experience and pre-draft ratings only. It may seem dumb, but it is not illogical because fans are asking this question.
