Typical "I have seen and played for long, so I know better" syndrome.
Bias takes place in various ways. Playing the game with some one is obviously one. I have bowled to Kumar few occasions in late 90s, and had come better of him. That makes me think that de Silva is the best test batsman SL had, because my experience with Kumar is always under estimating him. But looking at their records it's obvious who is the best.
Watching the game is different, and I never said watching the games will skew your judgment in a short term. But comparing what you have seen 30 years back to now and taking judgments out of it is rubbish. Because in 30 years your thinking pattern changes, judgments change, values change, your sensations diminish, but yet you don't want to accept that it has happened, hence thinking your comparison is unbiased and perfect, which is far fro the truth. If somebody gives me an account of Lillee vs Hadlee I would give a lot of importance to that account because they played in same era and the judgment was made by a person who has changed a little. But somebody comparing Trueman to McGrath doesn't carry that weight, because the bias of change has crept in.
The sarcasm is used by lot of the people with above syndrome when they have run out of arguments. It's like after eating everything on the plate muttering and banging the plate. And it does show in this instance Burgery don't want to read before posting. For his benefit here is what I've said about the particular instance.
So mate, watch the game and form opinions, it is fine. But back up them with suitable evidence or otherwise they'll be termed
delusions.
