I don't see anything wrong in having an opinion on what you see on the tele.
I have never spoken about how a live game went with anybody that has gone to a match. Simply because the last big match I went to was at was Pompy/Lincoln in 1973. That was quite alot for me.
However, I do listen to match commentators from part way around the world and thats good enough for me. 90% of the time I have agreed with them.
I do sometimes get to talk to somebody about a match that they see on the tele because thats all they can manage to do. There are lots of us about, sometimes.
I am now going to place a bet with my mate on getting quoted.
