Lotsa Baker Mayfield hate . . . from where, I dunno. We have women beaters and criminals of all kinds in the NFL that don't get that kind of hate.
He stunk last year, but he was injured and probably shouldn't have played. Go back a year to 2020 and his stats were essentially the same as . . . Matthew Stafford. Better than Kyler Murray, Rapelisberger, Matt Ryan, Jimmy G, Joe Burrow, Jared Goff . . . and a bunch of others.
No NFL team is pursuing him now because they all know that the Browns will eventually have to release him and then he can be picked up for free. So why would anyone agree to give up any assets for him, or even pick up guaranteed salary, when it's only a matter of time until he costs nothing? I will bet ANYONE here that there is interest by more than one NFL team as soon as that happens.
I could give two craps about him personally. And not a Browns fan, either. But the cheap piling on is . . . cheap.
I am not a Mayfield hater! I could care less. Did you see the

? That means "I'm joking."
That said, I think Mayfield has made his own bed. That's why I am okay with kidding around about him, and don't feel badly for him. I've never seen anything to make me think he is a 'team player'. He runs his mouth and does antics that give his opponents extra incentive - potentially hurting his team's chances of success.
I'm sorry that you think my joking around about Mayfield is cheap, I disagree.
To me "cheap" is unsportsmanlike antics like:
1. burying the Oklahoma "battle spear", and in other instances, Oklahoma flag - in the opponents logo at the 50-year-line...
2. taunting his opponents with profanity and his trademark "crotch grab"
3. March 2017 - he gets drunk and ends up getting taken to the ground by a cop
4. 2014 - gets rowdy and maniacal, ends up being kicked out of a Lubbock, TX restaurant
5. He keeps a list of "media members who have doubted him", people who have disrespected him, and other 'enemies'. After hearing threats against their players, one team paid a private investigator to keep tabs on him to make sure he wasn't going to actually attack any of them.
People have not infrequently drawn comparisons between Mayfield, Ryan Leaf and Johnny Manziel.
In 2020, the year you cited, he was 15th in passing TDs, 18th in yards passing and 31st in completion percentage. Not too bad, if it weren't for the character issues.
