Why is that? We've seen them for the past 3 years whats going to change this year? Well, most college footballers play their best in their senior season, especially ones with lots of starting experience. Coleman made notable improvement in coverage last season, IMO, and I expect he will build on that. Russell showed good coverage skills before his knee injury, but hasn't gotten back to that point. Even in his "brick hands" season, he was mostly in position, just couldn't hold on to the ball. Last year, AR did not play up to his ability, but I think he will rebound. The skills are there, he just needs to show them on a consistent basis. Hines will be a good addition to the group. He can run with most WRs, he just needs to show more maturity, which is reasonable for a player entering his second year of significant playing time. Add to all that, they should not be forced to hold coverage quite as long, with the improved D-line. I'm not expecting them to be ball hawks, but I think they can control the middle of the field and offer support to the CBs.
