Agreed about Cowie, as much as I don't rate Davidson good enough for Scotland at least he has age on his side and has plenty time to improve. Don Cowie is approaching 30 and shite.
As for Mackail-Smith, obviously I want Scotland to have the best players available to them in the team so why call him up as a replacement for someone who pulled out and put him on ahead of someone who was in your original pool of strikers?! (Maguire)
