There was a time when running backs were selected high in the annual draft, but that's not the case now. Free agents have trouble landing a big contract. Teams know that they can replace them with a cheaper version from the draft or undrafted free agents.

Jets RB Chris Johnson found that out after they released him. He signed a 2 year/$8 million contract last year, but was a disappointment after he posted the worst numbers of his career. He rushed for 2,006 yards in 2009, but only carried 155 times for 665 yards in 2014.

At 29, he is being thrown onto the scrap heap. He will probably find a job, but will need to sign for the veteran minimum if he wants to keep playing.
