Might want to rein in expectations a bit. From Barrows:
The one-on-one blocking drills between the offensive and defensive lines drew the attention of general manager Trent Baalke. As you would expect, newcomer (to the sport of football) Lawrence Okoye easily was handled by the offensive linemen, mostly Al Netter, who is playing center in this camp.
What's already evident is that Okoye has a gift for getting off the line of scrimmage quickly. That is, the explosion needed by a discus thrower translates to bursting off the line of scrimmage as a defensive lineman. He also tried a spin move that was absurdly good for someone his size who just began practicing football on Friday. What also stands out, however, is that Okoye has long - very long - legs. In fact, the only 49er who can compare in leg length is Alex Boone. The challenge for Okoye and mentor Jim Tomsula will be combining his quickness and innate athletic ability with an understanding of leverage.

If Netter is handling him easily, Okoye still has a LOOOOONG way to go. Granted he's got tons of room to improve. We shall see.
I think this is to be expected. I'm sure no one expected him to challenge Justin Smith this year. How to attack an OL is a teachable/learnable skill however.
What I take out of this little blurb isn't that he struggled with Netter, but that he is already showing a great burst at the snap and seems to have a very good spin move without any real teaching on it. Getting off the ball is not a teachable/learnable skill. If he's coachable, and by all accounts he is, then he should develop nicely. Will he ever be roster material? I have no idea. But anyone who expects great insights into what he can or can't be based off 2 days of practice in shells (first time ever for Okoye on the "pitch") is lying to himself (or herself).
