Purdy has played against 4 of the worst defenses in the NFL and has a plethora of riches around him. He’s probably definitely better than “last player drafted,” but he’s not as good as he’s been playing.
Being the quarterback of the Bears this year, and being the quarterback of the 49ers couldn’t be more diametrically opposed. One guy literally had the least support in the league, and the other probably the most.
So if the sample size on Purdy is its too small to consider whether he's really good or not, fair enough.
The sample size on Fields is large enough to conclude he sucks.
And the sample size of the Bears organization since 2020, compared to the 49ers organization in 2020, is enough to conclude they have no idea what they are doing.
Rebuilds don't take 3 years in the NFL. Period
