Op since you are talking about sport, I advise you to move the thread to Gambling discussion. 10 yrs on sport knowledge means you can be a sport panorama, by now you supposed know the merits and demerits of sport betting. Your update will be nice for many because many of us are not watching NBA frequently but once a while.
Op sorry to ask, which of the community are you planning to build?

Since you are a sport expert, you would have dropped some tips on the OP for users to evaluate their opinion on the tips about some sports.
