Also completely disagree that QBs are a lottery. Looking at the Super Bowl winners (with or without Brady) doesn't paint the full picture. The best QBs in the NFL are consistently chosen in the first round (Rodgers, Mahomes, Watson, Allen, Murray, Lamar, Tannehill, Ryan, Stafford, Mayfield, ...).
It's no sure thing of course but the hit rate is way higher for first-round QBs than QBs outside of it. Out of the 5 projected in the first round there obviously can be 2 busts (or even 3) but if you take the next tier of QBs (Trask, Mond, Newman, Mills) it's not even sure that one will make it as an NFL starter whereas that's almost guaranteed out of the first 5 projected ones. Yeah one of them can be the next Wilson or Prescott but much more unlikely and much more uncertainty with your pick in that case.
