To be fair Alex, Callum Paterson plays right back and so does Bardlsey so seems a straightforward swap. - I wouldn't go anywhere near Ricky Foster at Rangers. I was at the Hearts vs Dumbarton game last month and Paterson was superb throughout.
What baffles me more, how does Steven Whittaker get ahead of Graeme? Andrew Robertson deservedly number 1 with Graeme number 2 would be my choice and that's not through ICT tinted glasses.
Bardsley when called upon will play either right or left back. Shinnie also can do a job either side as we know. I also agree with your point on Whittaker. I genuinely don't think I've seen him have a good game in a Scotland shirt!
