I thought Lock looked pretty good against the Vikings. He had that one bad interception where he was a little late with the throw. But other than that he looked much better than last year. Instead of constantly forcing the ball into tight windows he was patient and showed a willingness to hit his check down. Both of his TD passes were elite throws and he showed great touch on the wheel route to his RB. I'm not saying that there's now competition at QB, but Lock's performance was encouraging.
