Lance has a lot of the physical tools and abilities that you want in an NFL QB. He's 6' 4", 225lbs. He has a really strong arm, he's pretty accurate. Lots of things to like. The problem is that he makes bad decisions or doesn't see things very well and I'm not sure which it is or if it can be coached out of him. So far, nobody has really tried.
The 49ers had just been to the Super Bowl 2 years earlier with Garappolo, then he got injured in 2020 so they drafted Lance in 2021. But I don't think they ever really gave him any real coaching and just expected him to be the guy because they drafted him to be the guy. When he couldn't beat out Garappolo as a rookie, they shelved him for the year. When Purdy came around and could play, they ditched both of them.
So he gets to the Cowboys after not having really played any real football for a couple of years and having to learn a new system behind an entrenched starter and a backup that knew the system already, he only got reps with the worst players on the team.
That all started in 2021 before is 21st birthday. He's been in the league 4 years and turns 25 in May. What was he supposed to do under those circumstances?
Now don't take that as an endorsement at all. I have NO IDEA if he can turn the light on or not. He may be one of those guys that can't, but I'm not sure he's ever been given a legit chance to be developed into a productive player. Scott Tolzien on the other hand would know. Which is why I suggested it.
