I’ll do you one better. I do not think the offense is as QB friendly as everyone thinks. The 49ers with a stacked roster has made it seem like they can plug and play a QB and still be elite, but so far the only very successful QB’s in the Shanahan offense we’ve seen as of today are Tua, Matt Stafford, Matt Ryan, Aaron Rodgers, and Brock Purdy. What do all of these QB’s have in common? Being able to play at a high level in the pocket, have teams committed to the run, and all but Tua and Brock were vets when first introduced to the offense. Fields would be setup much better with a Greg Roman type of offense or a Andy Reid-esque where the QB is allowed a lot of freedom to improvise. Unironically, Matt Nagy was probably the better coach for Fields but we ran him out of town.
