Baker makes better multimedia commercials. I cannot argue that fact.
Baker has had much more playing time, behind a much better O line.
RBs were a Baker advantage, and Javonte Williams looked tired at the end of 2021.
Lock is more of an unknown, because of the 2020 protocols, and because of the decision(questioned by most Bronco fans) to start Bridgewater in 2021.
Baker's 2021 Green Bay performance was worse than any Lock performance I've seen. Maybe that Lambeu game was the result of injury, but then maybe Baker will be injured more frequently, and will end up in the blue tent, often, like Cam Newton.
Edit: Baker's 4th INT may have been unfair(Rasul Douglas was holding) but at least 1 second half INT was accidentally avoided, and the 3 first half INTs were not good. And he looks like a guy who's too small and taking a beating.
The youtube video probably doesn't show him staggerilng at the end of the 2020 Colts game, but he certainly looked knocked out.
Lock is not an "unknown". He's started over a seasons worth of games and he's been in the league for three years at this point. He's a veteran that hasn't had much success in the NFL. You can blame it on a variety of things, but overall he still looks like the same guy his scouting report described when he was drafted. He hasn't had much in the way of improvement. Lock is a below average passer at this point and that's all he is. At this moment in time he's losing to Geno Smith in training camp.
If these reports are right, it's not exactly reassuring regarding Lock. If he and Geno did look good, why are we still flirting with Baker Mayfield?
On Mayfield, the Browns haven't exactly been managed well. Since he's been there he's had a new OC every single one of his years. This is an excuse I often see for Lock, but Mayfield hasn't had much in the way of stability (and he's looked better than Lock in game). He's had a new HC every other year on the Browns and a rotating FO.
Lock and Mayfield are BOTH knowns. Lock is a backup tier QB and Mayfield is a hot and cold QB but still more consistent than Lock, or Geno for that matter. It's not even a question whether or not he's better than Geno or Lock, nobody outside of the Seahawks fandom would support that assertion and for good reason.
That being said, I don't care whether we trade for him or not. He's very much so a miniature Wilson in the way he plays. He has some of the same strengths and weaknesses, only he's not as good. Baker Mayfield is essentially Russell Wilson in the second half of 2020, a frustratingly inconsistent QB with a few hot streaks and plays. In fact, Wilson's numbers from the second half of 2020 looked oddly similar to Mayfields.
Ultimately I think Mayfield is a QB that is worth kicking the tires on, provided that Browns eat some of his cap for this one season. That being said --- I'm also afraid that he'll do enough to stick around and end up being Kirk Cousins, a QB that isn't bad enough to let go of but also not good enough to win you games. In a sense I would prefer Lock and Geno for potential future QB's but I'm also not opposed to trading for Mayfield for the right price. He's definitely an upgrade, but ultimately he's a guy that i think would lead us to the same place as Wilson, one and done in the playoffs.
