The Facts: According to ESPN.com's Rich Cimini, Johnson will change the dynamics of the Jets' rushing game. For years, they've been a predictable, five-hole attack, with the likes of Chris Ivory and Shonn Greene pounding away between the tackles. Because of his speed to the outside -- the man once raced a cheetah on TV -- Johnson can stretch a defense horizontally. That will soften the belly of the defense. "He's unique because, at any moment, he can score," Hall of Famer Curtis Martin said.

Diehards Line: Johnson has 12 rushes of 50-plus yards since 2008, second only to Peterson (17), according to ESPN Stats & Information. Johnson didn't break any long highlight-film runs last year but his mere presence forced opponents to crowd the line of scrimmage. Only two backs, Adrian Peterson and Frank Gore, ran against more eight-man fronts in 2013. And as Cimini pointed out, it's a threat the Jets haven't had under Rex Ryan. It's a threat that should help Geno Smith as well. Cimini is certainly sold, calling the 28-year old Johnson "the Jets' most accomplished skill-position player since LaDainian Tomlinson." Fantasy football owners are well aware, Tomlinson was past his prime upon arrival in New York. Johnson might be in the same boat.
