Baker Mayfield seems like the kind of QB who people would LOVE if he was an undrafted FA who managed to land a starting job - but he was a number 1 overall pick and you think, I don't know - we should try and find someone better. But I do think he can last another 10-years as a stop-gap QB. One of those guys who has talent enough to keep whatever team he's on from having a high enough pick to draft a better option.
It's more that you have NO idea what you're getting week to week, and there's little logic to why he struggles or succeeds one week to another. He seems moody both on and off the field and it shows in the way he plays.
He and Gardner Minshew are in the same category.
