This is true. McNabb wasn’t a schlub. Andy Reid is great coach and Mahomes is a great QB. Some of the comments around KC is “It’s not Mahomes it’s Andy”, which I think is nuts.
Reid doesn’t have a Shanahan track record where he’s gotten very real NFL production out of Beathard, Mullens, and now Purdy. Literally 3rd string QB after 3rd string QB.
