AJ McCarron’s path to unrestricted free agency was far from conventional, but it will likely be a venture for the quarterback that ends up with a chance to compete for a starting role.

Oakland’s signing of Martin, also known as the “Muscle Hamster” due to his 5-foot-9, 223-pound frame, is intriguing.

Martin has been a lead back his entire six-year NFL career, and returning Raiders coach Jon Gruden has said he looks forward to coaching Marshawn Lynch, who is due a $1 million roster bonus on Sunday.

Lynch posted a cryptic tweet on Wednesday.

Still, Gruden could be trying to replicate the Thunder and Lightning backfield from his first tenure as Raiders coach, with Lynch and Martin playing the roles of Tyrone Wheatley and Napoleon Kaufman.

Or Martin could be the Raiders’ new lead back.

Martin, who was born in Oakland and grew up in Stockton, California, told reporters Thursday, “This is my homecoming.” He said that he met Lynch after his rookie year at the Pro Bowl and “can’t wait to pick his brain and watch him and see how he plays the game and practices and all that.” Martin said he will accept whatever role the Raiders need him to play and called Lynch “a great back.” “He’s definitely made his mark in the league.

Based upon the staggering $114 million Bradford has earned in eight previous NFL seasons, Arizona now joins the Rams, Eagles and Vikings as teams who spent big bucks believing he could be a bona fide franchise QB.

There were flashes. Those three clubs saw the prototype size (6-4, 222 pounds), good arm strength and accuracy that helped Bradford dink-and-dunk his way to a then-NFL record 71.6 completion percentage with Minnesota in 2016.

“We have definitely moved on to a different and perhaps more difficult stage of this whole process. We’re thrilled in the amount of progress we’ve made in the last year, in the talent and even the camaraderie that these players have shown,” Hahn said.
