This really scares me off of Locker, even though I've never heard of Russ Lande. Apparently he's best known for giving Brady and Bulger high grades pre-draft. He said,
"...I think Jake Locker hurt himself, I really do. There’s no question physically that he’s got all the tools. He’s got good mechanics, but his accuracy is terrible. I know I spoke to a coach today to get his opinion and he said if a guy’s mechanics are good and he’s smart enough, but his accuracy stinks then there’s not a lot you can do. You’re pretty much saying that you’re always going to have an inaccurate thrower. And if you can’t be accurate you cannot be a quarterback in the N.F.L. I think Locker hurt himself a lot this week...Aaron Rodgers, who coming out of college couldn’t move defenders. He was very good technically, he could throw the ball, but he couldn’t get the safety to move with his eyes. Now you watch him and he’s one of the best at pulling a guy [out of position to create an open area for a receiver].
That’s something that Jake Locker has improved upon, but the problem is that you can do all the work you want and improve in every area and if you’re inaccurate it doesn’t matter. That’s the problem with him. I love him. I want him to succeed – he’s a great kid – but he’s not accurate and I think that’s going to be his downfall.
I don’t think he’s going to be a starting quarterback in the N.F.L."
