Johnson flew under the radar despite playing in the same backfield as Marshawn Lynch in high school. He earned the backup job right away at USD, but did not see much action in 2004. As a sophomore in 2005, he burst on to the scene throwing for 3,256 yards while completing over 70% of his passes for 36 touchdowns and eight interceptions. As a junior, Johnson threw for 3,320 yards with a 66.3 completion percentage for 34 touchdowns and just five interceptions. He became a three time all american as a senior, throwing for 2,988 yards while completing 68.4% of his passes with an amazing ratio of 43 touchdowns to just one interception.
Johnson has been ridiculously efficient during his college career. He has shown to take what the defense gives him and the accuracy to complete all the throws. Domination is an understatement with the type of numbers he put up at his level. Johnson is also a legitimate rushing threat. He is a great athlete with excellent speed and can buy more time and escape the rush, or tuck it and big up big chunks of yardage. Johnson has a ton of upside and has all the tools to develop into a quality NFL QB.
Johnson has average size, even when he weighed in at 214lbs. He will need to get stronger to better handle the beating NFL QB’s take. He will also need some time to develop his overall skill. Despite working with Jim Harbaugh during his college career, he still needs some mechanical work and needs time adjusting to an NFL playbook.
Johnson is a kid who dominated at his level, showcasing the talent to play on Sundays. He then had an excellent combine from an athletic standpoint and raised some eyebrows. He will need some time to develop, but if a team is willing to wait, he could be big time in a few years.
