SOD has got where he is by being a solid if unspectacular full back. He just played the game of his life at Wembley and was part of Scotland's best away result (over 90 mins at least!) in 15 years in Vienna..even if no longer first choice, he's in the squad for a side a couple of playoff games from the WC finals. Do you really think that at this point he suddenly goes 'nah, I'll just jog it in each week for Motherwell'?

He effectively had no break/pre-season before going straight into the LC groups, he's had corona, he's got a young family, we play a 4-3-3 which hangs the full backs out to dry, he doesn't seem to suit captaincy...Like you I'm just guessing the reason behind his slumping but I think one of those or a combination of a couple is much more likely than a previously reliable pro has suddenly decided he can't be bothered.
