Bring back SAF from his retirement and he'll be able to tackle the Scotland job 'in his sleep'! 
But seriously speaking, I can reflect back to the Scotland situation, pre Strachan, and I must say the improvement in organisation, team spirit, commitment is significant. Wee Gordon has an average squad of players to utilise and even the ignored players, who are being mentioned, are not world beaters but one or two of them may offer something different for Strachan to consider. One thing he will be doing is observing most of these players and setting up his 'pecking order' of his preferred players based on these regular observations/reports That's how it works! It's a pity we don't have one truly world class player to call on but that's life.
