Again I think it depends on your league size and maybe even scoring system. I just checked our league... on the season he's ranked 15th among QBs... 19th over last 5 weeks.
I was mildly surprised when I checked our league scoring system - in years past guys like Brady, Rodgers and even Newton were set it and forget it type guys. This year:
Tier 1 - Mahomes
Tier 2 - Brees, Luck, Roethlisberger, Ryan, Goff
Tier 3 - Newton, Rivers, Cousins, Rodgers, Trubisky, Watson, Wilson, Brady
Tier 4 - Fitzpatrick, Dalton, Prescott, Wentz, Mayfield, Manning, Stafford, Bortles, Carr, Keenum
then everyone else
What is startling is that Fitzpatrick is roughly equivalent to Brady (ranked 14th among qbs) and Rodgers is sandwiched between Cousins and Trubisky - a far cry from expectations on draft day.
