There is quite a bit of lag between new cases and new deaths (at least 2-3 weeks generally). We also know more about the virus now and ways to treat it, than we did in March/April, so that itself will decrease the amount of deaths. Increases in new cases is certainly due to more testing, but the rate of positivity is the concern. We're seeing big spikes in positivity rates and that most assuredly will lead to a spike in deaths. Several states are already reporting their highest COVID hospitalizations since the pandemic began. Unfortunately, it's very likely new deaths will have a sharp rise in the next couple weeks. It's very likely at this point that sports will at least start their seasons with no fans. The Novac Djokovic tournament is a prime example of the sort of risk you present and the type of blowback that will be incurred in a worst case scenario situation. The best chance for sports (and everything else) to get back to normal is for a valid treatment/vaccine to be developed. Maybe I'm wrong and new deaths will continue to drop. That would certainly be the most optimal scenario.
