The more information we manage to get about the teams, the better our bets should be. In my opinion investing time into research and staying up to date on our favourite teams will pay off. If we are a big fan of our home team it happens naturally that we are well informed
We just need to make sure we are also looking at the other teams. Also once information about the sport gets published we should assume that most betters are looking at it.
The information we get is important but it is even more important to be able to process that information relatively quickly and be able to give specific odds to that information, after all the odds move for a lot of reasons and some of them have nothing to do with that information and instead have to do simply with the way the casinos have to balance their books, if you are able to find a discrepancy between the actual odds of an event happening and the odds being offered you are bound to find good bets in which you have a slight edge over the casino.
