People say don't change a winning team, but if Bentley was injured but we still won, I'm sure they'd be like "well thanks Ted (Smith, Tes, whoever) but Bentley comes back in." It'd be the same with Timlin, Corr, Coker et al.
Pick your best team, not a winning team.
Having said that, at this moment in time Leonard is holding down the right back position and White hasn't played for nearly a month. I don't rate JW particularly highly and Leonard has some attributes that JW doesn't have. Also, JW played through a knock during our playoff campaign last season and he was well below par.
Very true point, however Leonard's come back into that position to cover and he's earned the shirt (as did Deegan & Atkinson). To drop him after his recent performances just because John White is available, would be very harsh on him in my opinion.
