When you are the #1 overall pick in the draft, I don't think it's unfair to hold someone to a higher standard.
Four years is plenty of sample size for a QB. Baker was behind Daniel fricken Jones in two of his healthy years in QBR.
He's been supported by a great running game and has enjoyed plus weapons with guys like Jarvis Landry, Odell and one of the better TEs in the league in
David Njoku. If you want to say he's a serviceable QB, sure, go ahead. The Browns clearly feel like he wasn't their guy and sold a TON to bring in a controversial franchise QB to replace their former #1 overall pick. Idk what else to tell you.
Again, I've alread laid out my bias towards the guy, never liked his cocksure attitude at OU and have no love for him. But I believe there's a reason why teams haven't been clamoring for his services after the QB carousal has already spun this offseason. But I digress...
