I think it was true in a lot more than a season or two, to be fair. There have been a number of seasons where we have had great results against the challengers at the top, but then followed it up with lost points against teams much further down the table. This had been a source of frustration for a long time.
I think it happens with every team though, but LFC fans notice it more when it's us. A bit like how all football supporters seem to have the impression their own team are poor from set pieces, until pointed to stats that show that they actually compare well with other teams.
For example with the 08/09 team, I agree in isolation that there were a few draws too many, and that's where we could have done better if anywhere. But we did also swing quite a few games our way with dramatic late winners from the likes of Kuyt. And we did manage 86 points with both Gerrard and Torres missing quite a few games through injury (at a time when we were called a two man team). So it's more fair IMO to remember it overall as an impressive achievement to reach that points total, than primarily as a season where we threw away too many points.
