The NFL has to clean up their obvious bias towards certain quarterbacks and their obvious bias against certain quarterbacks. And trust me, Stafford is not one of the favored ones.
I've seen Mahomes fake going out of bounds and wind up with more yards. If I'm a defender, no use in tapping him along the sideline and getting 15 yards. Might as well piledrive him into the ground and make the 15 yards worth it. For some reason, Josh Allen gets treated like a princess with the calls.
I didn't care for Scam Newton, but he took a lot of hits without a penalty that would draw a multitude of flags had it been Brady, Mahomes or Allen. Even Purdy gets some ticky tack calls in his favor.
Then I see Stafford get plowed from behind in a playoff game, face masked where his head turns and no flags and I wonder if the refs have some narrative to carry out. Sort of like how the iggles false start like 40% of the time in tush push mode and I've never seen them flagged for a false start.
