Probably, for some bettors studying different sports can develop their betting mind just as you have exactly explained but personal, watching just my favorite sports like football, tennis, boxing, wrestling is even more than enough to give me the idea and knowledge I need to become a good bettors who make accurate analysis and have successful bet most times while sometimes too tables could turn. I really do not believe that in order for someone's betting mindset to improve they need to study different sports.
