Yeah, and they'll use anything they can come up with as a knock on him. This season, it's the fumbles.
I counter that argument by pointing out he was on a team with a mediocre or worse OL, and he was sacked 34 times. He had 8 fumbles, 6 of those were sack fumbles. He lost 5 fumbles.
Who else had 8 fumbles? CJ Stroud and Baker Mayfield, both of whom people are crowing about their great seasons. Who had more than 8 fumbles? 11 QBs. I won't list them all, but you've heard of them. Just a few: Lamar Jackson, Tua Tagovailoa, Trevor Lawrence, Russell Wilson, Jordan Love, and Jalen Hurts. Nobody's talking any of them down. Hell, Kirk Cousins had 7 fumbles in only 8 games and damn near everyone thinks the Vikings should re-sign him.
Tua, Hurts, and WIlson also lost 5 fumbles. 6 QBs lost more, including Lawrence (7) and Jackson (6).
When you look at that, it's pretty ridiculous to hold GM's 8 fumbles against him. He threw for 3,300 yards on a team with only 1 1/2 reliable receivers and an inconsistent run game
