Yes, my only issue with Blackmore is that he fully bought in to the EFL report and was particulalry forceful in his opinions. I cannot believe for a minute that Tonda isn't aware of his views at the time.
When the FA report came out and corrected a ton of mis-information then yes, Blackmore should have looked up and admitted he was wrong and totally bought the EFL narrative over the clubs view.
As has been stated before he's had a bit of a nightmare over Spygate. His audience is Southampton related, he can have his opinions of course but in his position maybe you should just balance that out somewhat publicly if not privately.
