There is an option to analyze compared to luck-based games in casinos so why not take the oportunty to learn about the team the stats and the likely outcome there is some sense of completeness as a sports bettor if you get the analysis right.
We are gambling for gratification and fun its ok to go for profit but if you can have both its a great feeling so I go for analysing my bets but there's no harm in comparing your analysis to other experts and try to reconcile your analusis to their analysis.
