Seriously though they didn't invent anything new. As
@Sicilian said Jackson is just a freak and extremely elusive & fast. Plus even though he's taken a few, he avoids the big hit better than most anyone no matter the position. Just great awareness in the pocket, on the run, really no matter where he is.
A few years ago they had lightening in a bottle. Last year the OL regressed to the point where it was an accomplishment to get a snap off without incident. TE's regressed. Bottom 5 WR corp (yes maybe worse than ours) . Lamar obviously wasn't as great but he's incredibly efficient overall (26/9) and still was the best player on the team, leading them to the post-season.
He still has trouble throwing outside the #'s and might always have issues there but you have to do better than Willie Snead as your most consistent target.
He's one of the best anticipatory passers when it comes to the MOF btw
He definitely has his flaws but you accept those bc he's a "Z" type athlete that stands out among the best of the best.
Also lets stop calling him a "running QB" or anything stupid like that and address real concerns bc he has them. No need to make stuff up. He obviously runs but that's a 2nd/3rd option unless it's designed. Not bc he can't read a defense ir anything like that. He's a pocket passer (flawed like 98% of the QB's in the league) who can run. And he'd be a fool not to use everything available to him in that respect.
That said he's their entire offense and been the biggest reason why they've been to playoffs 3 years in a row.
He's been the best QB in his division for a few years ..
And his draft class so far ...
Highest comp% - passer rating - YPA, 4th in yards, last in INT (18) among big names, sacked the least among Allen, Darnold, Baker, most W/least L (if that's your thing), rushing yards/rushing yards attempt, rushing yards game.
