As of the end of last season, we did not have anyone better than Grixby. However, that does not mean that Jones or some of the other corners could not pass him with hard work in the offseason. In my eyes, Grixby has peaked at his potental. Jones, Murrilo, and Bowman all have more room to improve which may help them move past Grixby on the depth chart. But they first must become better than him and not just be placed out there in front of Grixby because of their potential.
