Much more upside to Johnson than Mims. Granted, the only highlights of Mims were on OL instead of DL, but he counts a lot on his stature and upper body strength against smaller competition at the high school level; like to see him try that against the big boys in college and see how it works out. Johnson has great acceleration and has good hands. Work on his strength a bit once he gets here and he could turn into a decent player at the worst. My 2 cents.
