Jamaal Charles (RB)

The Denver Broncos know more than many teams what running back Jamaal Charles is capable of doing, when he is on the field. Playing within the AFC West, the Broncos have prepared for Charles over the past seven seasons. The problem is that the 30-year-old runner has played exactly eight games over the past two seasons.

Charles is trying to return from a second ACL tear, and he has struggled to get back to form. The Broncos may look to sign another running back in free agency, as their run game was among the league’s worst. Charles won’t be the answer.
