Don't look at the accuracy. Look at how their analysis was made.
If you know sports, you can actually say if their analysis can be considered as valid or not. Don't rely on chances even how good the sit or tipster is.
But there is sense in what you've said. If the analysis is considerably fair and good, it's also a good basis to look at the analysis.
@OP look for the soccer prediction/discussion threads on Gambling Discussion, it's not that someone's going to give you prediction but you can read what are the others thought for a certain soccer game.
