The signing of Johnson makes a lot of sense for the Jets as he adds desperately needed explosive playmaking ability to New York's running back group. The player formerly known as CJ2K (for his 2,000 yard rushing season) will split carries with Chris Ivory and could be featured in the passing game as a receiver out of the backfield.
With Chris Johnson now in the fold the Jets can focus their attention on adding wide receiver and tight end help in the draft. Bilal Powell will fall into the third back slot for the Jets with Mike Goodson and Alex Green on the potential chopping block. (In all honesty I would not be surprised to see Gang Green draft a young explosive back and then cut both Green and Goodson.)
Idzik putting together his puzzle
For all of the criticism general manager John Idzik has received this offseason, the Jets gm has quietly pieced together a solid team. Idzik has signed arguably the best free agent wide receiver (Decker), quarterback (Vick), and running back (Johnson). In addition New York's general manager re-signed several valuable players including Jeff Cumberland, Garrett McIntyre, Darrin Walls, Leger Douzable, Willie Colon, and Calvin Pace.
Slowly but surely John Idzik is adding the playmakers that his team needs. Supplement the free agent signings with a solid draft class and the Jets will be building a sound foundation for sustainable success. Not sure what else you could want from the New York Jets front office. This team is showing financial responsibility with a keen eye on the future. Sounds like a recipe for success to me.
