"I think I'm going to fit in pretty well," Johnson told the team's official website. "Just talking to (offensive coordinator Marty Mornhinweg) and to (coach) Rex (Ryan), who's a guy that likes to run the ball, I think I'm going to fit in very well. We talked about all those things, catching out of the backfield, getting the ball to me in space."
Johnson's pass-catching ability is another reason the Jets signed him. He's not a prolific receiver, but he averages 45 receptions per season. With 42 catches last season, he was one shy of the Jets' team leader, wide receiver Jeremy Kerley. Johnson had as many receiving touchdowns as any player on the Jets.
Once known as CJ2K, Johnson brings star power to the position, the first true breakaway back of the Ryan era. Ryan coached Thomas Jones and LaDainian Tomlinson, both accomplished runners, but they weren't home run threats.
Some will argue that Johnson no longer has that dimension, as he managed only five runs of at least 20 yards last season.
There has been a dramatic decline in all aspects of his game since 2011, when he signed a four-year, $53.5 million contract extension.
Shaky offensive-line play, a change in offensive coordinators and the knee injury contributed to Johnson's downturn, but scouts also have noticed that he's not as elusive as he once was. He doesn't force as many missed tackles as he did in his vintage seasons. In 2009, the year he dominated the league, he had 22 runs of at least 20 yards.
