But those streaks have been there as long as I know NBA 2k (which is only wk9 but still). If your team gets on a slump or the other on a run, try not to rush anything, call timeouts, try different tactics. If you're missing wide open jumpers, try some plays to get to the basket and get your guys going again before you take more jumpers.
Those methods don't work 100% of the time but overall this hasn't been that big of a problem to me.
