Do any of us know if Duncan was 100% fit today, how he trained on Thursday or any other reason why he may have chosen to start him on the bench? I would venture to suggest that the answer to that is a resounding NO!!
I've read some sh*t on here in my time but this is an absolute belter. Aside from the fact that Duncan looked ok as he skated past 4 players the first time he got the ball you're suggesting that how he trained on Thursday may have been a factor?
If Duncan Watmore trained so badly on Thursday that despite us only having 11 fit outfield players, including a loanee debutant, and the other 2 players who have played in his position (Richman and Lawrie) being unavailable/unfit to start to a standard that he could not get in the starting XI then the young lad needs his contract ripping up and taken outside to be shot - it would have been the worst training session in football history.
Taking the standpoint of devil's advocate does not mean you have to present such absolute rot and drivel!
