To be fair Sam has got plenty of time to become a grumpy SOB. Just wait until the stakes become higher.Actually I found Clarko's press conferences to be a bit meh towards the end of his tenure. He was such a professional coach all he would give the press was one of his favourite cliches "another solider, more polish, etc".
Whereas Sam seems to be refreshingly honest about where he thinks the list is and how he is going about building the team in his image. He doesn't go overboard but I feel like we have a real insight into what is happening within the club.
