..."huge difference" when comparing what matters(production):

P. Mahomes '20 stats:
4740 pass yds 38 TD 6 Int & approx 150 net rush yds 2 TD

J. Allen '20 stats:
4544 pass yds 37 TD 10 Int & approx 260 net rush yds 8 TD

K. Murray '20 stats:
3971 pass yds 26 TD 12 Int & approx 650 net rush yds 11 TD

This was in '20, KMs 2nd year. My point was in response to goblin's post suggesting he hasnt been healthy since rookie yr('19), yet he produced 2 Pro Bowl yrs in '20 & '21 and played all 16 in '20...


And if you compare his '21 PB yr stats, to the 2 AP QBs; Rodgers & Brady, KM was within 100 total net yds(pass & net rush) of Rodgers & only 1 Passing Efficiency point behind Brady(102 vs 101). And he only played 14 reg season gms compared to 16 for Rodgers & Brady.

So production wise, not a "huge difference" in KMs PB yrs compared to the AP QBs.

I'll also say I don't believe KM is on Brady, Rodgers or Mahomes level yet, and may never be, but he's certainly in the same group as several of the QBs listed in this thread(EG Herbert, Tua, Prescott, Purdy). Not to mention he's arguably the greatest true athlete to ever play QB in the NFL. EG considering he was a MLB Lottery top 10 draft pick in college...
