Has a child. Was also a linebacker and defensive end as a Texas prep in addition to playing power forward in basketball and a sprinter on the track team. Redshirted in 2007. Tied the freshman rushing touchdown mark in ’08 after carrying 76 times for 338 yards (4.4-yard average) and 12 touchdowns in 13 games (two starts). Saw action in all 14 games in ’09, making one start at Baylor, and posted 87-335-12 (3.9) rushing and caught seven passes for 42 yards (6.0-yard average) and zero TDs. Rushed 134-592-6 (4.4) and caught 4-49-1 (12.3) in 11 contests (one start against Florida Atlantic) in ’10. Missed the UCLA game with an ankle injury. Played in 13 games in ’11, starting 10, and tallied 48-200-6 (4.2) rushing and 1-4-0 receiving.

Looks the part — thick and muscular with a sturdy trunk. Picks up steam and runs well in a straight line. Scored 36 career touchdowns. Good awareness in pass protection and has bulk to absorb a rusher. Reliable hands. Hardworking leader by example.

Was used sparingly in spread offense and was not a core special-teams player. Ordinary initial quickness. Linear movement skills. Builds to speed. Inconsistent pad level. Is not a blowup isolation blocker or sledgehammer short-yardage back. Needs to generate more power through his hips. Weight has fluctuated (as high as 270s).

A big, situational college running back, Johnson’s best chance to stick in the pros will be as a fullback. Has some tweener traits, but size, hands and intangibles give him an opportunity to convert.
