Only just reading this thread, and not sure what comes after but apart from swapping Potts and Browne around i wouldn't disagree with this.
Potts spends a lot of time on defensive duties and can get forward so i don't see why he wouldn't make a decent RB.
Browney, whether he likes it or not does not command or grasp central midfield anywhere near enough to warrant a place in that position but is mobile and energetic enough to play right side, which he should concentrate on. He has abilities but is not technical enough to dictate play.
As in many walks in life people/players don't want to be what they are and what they are good at but want to be something they are not.
Que Cera serra!
Life and Football is cyclical and 4-4-2 will make a comeback. So many Teams want to play 3-5-2 but just don't have the personnel and end up playing the defensive 5-3-2 (5-3-1-1)
