I would say there is a lot of people who would agree with Adams regarding the standard, also those who would argue he is wrong but all conversation surround the Scottish game is legit. Arguments on both sides would have a lot of substance. The issue I had with the interview is he doesn't make the point well and it doesn't come across as I thought out personal opinion that he can back up. It looks like he lost game of football because his players make a mistake and he tried to hit out at anyone and everyone like a child who had just been told they were getting ice cream after dinner.
The English comparison was poor IMO, I watch a lot of league 1 and championship football and I've watched some rotten games over the past 3 months.
Last thing on it would be that if he genuinely believes the standard of football is that bad in Scotland, what are his suggestions to improve it? not any good telling everyone how bad something is with no potential resolutions.
I think Derek Adams will regret the way he came across and probably shows again why interviewing managers directly after games is not also the best idea, especially when emotions are high.
