While I generally agree, I think making one all-star team a rising stars team will make things more interesting because I don't think players voted as all-stars will want to lose to the rising stars team (ego)
maybe but that will likely only help for one of the games, the other 2 will still probably be snoozefests. Also do you actually want to watch rising stars in an all star game? Isn't the whole point to watch all stars?
