I am guessing there is something at play here behind the scenes. Either he isn't a practice guy, doesn't have the right attitude, or maybe did something stupid he's been punished for, or SOMETHING along those lines. If not, we would have seen him get a few chances to make some plays by now considering the flashes he's shown. It isn't as simple as pass blocking, because he wouldn't be in on passing downs anyways. I guess itt could just be motivation, telling him he isn't going to play until he practice his ass off and prove he earns some of Turbin's snaps. However, I don't think even the greatest of motivational masterminds drafts a guy this talented with their first pick, sees some great flashes from him, and then just decides they don't want try him to see what he can do. There is a lesson being taught for undisclosed reasons.
