Shelton certainly did not pass the eye test for me playing for the Bears.
Remember he's a 7 year vet making the same mistakes. Body is developed out, less room for growth.
Limmer has more growth and more experience to gain.
Shelton has hit his ceiling. He is what he is.
His run blocking, especially at the second level is not something to train other lineman on. It is so bad that there are low light reels on this.
Watch Shelton's films and see if your eye test matches a 12 PFF ranking.
