Like others have said I'd like to see him at RT next to Trai Turner.
I think he has a solid future and could be a permanent fixture @ LG. He's better suited as a G and has the chance to be dominate there with proper coaching and conditioning. Silatolu is not the answer and will be in the last year of his rookie contract next season. With Norwell, Kalil and Turner, the interior of our OL will be set for some time.
