When our true fans hear it, we know what's what. It doesn't effect us, but as others have said, the casual observer will actually listen to what he says.
My old man bless him, well into his 60's now will have had us on in the back ground or will have watched bits will have had his mind made up by the commentary. He used to be a die hard fan, I had my first season ticket at 7 & he took me till I was old enough to go on my own. He lost interest but is now a casual observer, I gaurantee when I see him, he'll say something along the lines of 'well, that wasn't much cop was it?'.
Tyler is or could be considered bias, I think he just longs for the good old days, he's one of many that thought our product was the best, no doubt he hoped Pep would fail, Pep is making the established look very very daft.
