I think the biggest potential for a washout is Wilson for the Jets. First because he was the #2 overall pick and second the tire fire that has been the Jets organization itself for quite some time now. They always go after the biggest/best OL FA's every year and every year it's swing-and-a-miss. By the time that dust settles they're trying to plug holes with 3rd tier options. At the same time, in watching his college film, I saw an accurate QB with a bit of Rodgers to him with Wilson. The biggest worry with him is his size. He's hovering around 200lbs and is not going to hold up if he's continually getting hit.
I honestly think that Lance is in the best situation out of all the QB's drafted and that he's most likely to be the best QB of the class. We have all seen how much coaching matters with Josh and Lance couldn't ask for a better teacher of the game than Shanahan. He's maximized every QB handed to him. Lance also has a dynamic skillset that Shanahan with get to toy with. None of his prior QB's have had this kind of athleticism outside of Robert Griffin III. Lance is built with a much bigger frame and a stronger arm than Griffin had as well.
Lawrence and Meyer paired together? Meh, I like Trevor's chances better once Meyer steps away or gets fired.
Justin Fields has everything that you would want, but he's basically playing for a lame duck GM and coach. That could hurt his development.
Mac Jones is the highest floor, lowest ceiling QB of the bunch. He's smart, he's accurate, but there's nothing that you see him do that makes you say "wow" really. He will likely be a serviceable starter for NE in that McDaniels offense, dinking and dunking his way down the field. Reminds me of a Pennington type of QB.
