I think it has to do with who is behind him. Coleman doesn't play balls inside so the only way he can get it is by having it down the line and then he gets pinned in by the fullback. Coleman isn't great at supporting wingers with forward passing.
Nah, for me, he plays well as a RWB because the game is simple.
As a player, he has zero composure or intelligence.
He has a bit of athleticism and pace and can put in a good pass/cross.
When he is told that his one job is basically to run in a straight line, he does it well.
Anything else (like we saw v Leeds) and he can't cope. Unfortunately, that sums up half of the squad, too.
