Notes:
Three-time All-SEC performer...Had triple-digit tackles in 2009...Did his best work against the run, thanks to a 258-pound frame...Is strong enough to shed the blocks of linemen...More of a hammer than a natural athlete, Johnson doesn't change direction well and can be exposed by athletic tight ends in the passing game...Is a ferocious hitter who can get to the quarterback via the bull rush...Makes tackles in space and usually wraps his arms...Major concern is the multiple knee surgeries he endured in college.
