The Facts: Following up on a previous item. ... Adam Schefter of ESPN has reported that the Jets have “some concerns” about the knee, and that it contains arthritis. Johnson has said there’s no arthritis. Here’s what we know, from a source close to the situation. His knee is normal, for a player who has six years in the NFL at running back. Does his knee show wear and tear? Of course it does. Can he play on it? Of course he can.

Diehards Line: As PFT's Mike Florio further explained, Johnson's knee would look no different under close scrutiny than the knee of any other running back who has spent six years in the NFL with significant use. He has 2,014 regular-season offensive touches, an average of 335.6 per year. And if the Jets had concerns, why would they have signed him? G.M. John Idzik is conservative, thoughtful, and deliberate. He’s not going to roll the dice with $3 million of owner Woody Johnson’s money. “It flies in the face of common sense,” Florio's source said. ... So could the knee put a cap on the number of years that Johnson will be able to play? It's just not an immediate concern. In the end, it's another data point for fantasy football owners to consider as they assess CJ2K's role going forward in New York.
