Rosenior and Clyne should be considered as next in line for Right Back after Walker/Johnson, rather than playing Smalling or Jones out of position.
Nah Coat, Matt Lowton and Carl Jenkinson would be next in line in my opinion.
Lowton has been poor this season.
Joel Ward at Palarse on the other hand has been impressive.
Ward is currently playing in central midfield isn't he, with Mariappa at Right Back? Good point though, I'd maybe have him ahead of Lowton.
Unfortunately Hodgson's list is more...
Johnson
Walker
Smalling
Jones
England have no other right backs.
