One possible free-agent option for Denver is former Las Vegas Raiders quarterback Marcus Mariota. The No. overall pick in the 2015 NFL draft by Tennessee, Mariota never lived up to his draft pedigree for the Titans.
Brian Callahan's getting head-coaching looks but says none of that will impact Bengals' prep for playoff game vs. Titans.
Johnson hasn't had a chance to show what he can do as a returner, but he does show some desired traits you want in a returner when he works after the catch. He has good vision, burst to find a lane, and turn on the gas to get extra yards for the offense. As a late-round or undrafted option, he adds to the depth competition and another option to compete for returner duties.
