I don't think improving on Cromarties CB2 play from last season is outlandish
Apart from Revis, who is definitely better than Cromartie (regardless of whatever you feel about his play last year)?
Williams maybe but I'm leery of him after exposure. Skrine may do well outside under Bowles but his history says he's better as a nickle. After that, we have a group that struggles just to get on the field, never mind how they play once out there.
In a perfect world, Williams excels with the opportunity outside and Skrine can continue in his role from last year. But that's far from a sure thing. That's why we don't deserve to be ranked in the top half of the league at the position, no matter how good Revis is.
