Is this the US or UK?
Hard to see how anyone can estimate the number of cases when a high proportion are asymptomatic, but obviously it varies all over the world so I have no knowledge of your local situation.
As far as the UK goes, as much as I want the season to start tomorrow, whilst there are still hundreds of deaths a day I can't see how anyone can justify starting cricket fixtures.
Don't forget when we "locked down" (so to speak, because we didn't really do it properly) there was only a quarter of the number of deaths daily we're seeing currently, if anything we're coming out to quickly as it is (although I understand the economic reasoning).
The UK.
Maybe you haven't been following the analysis very closely. Deaths lag infections by up to 3 weeks, so hundreds of people dying yesterday reflects the infection rate at the start of the month, not now.
Surely you're aware that since lockdown, the number of infected has fallen by over 95%? Only 0.35% of the country are estimated to be currently infected, in some regions (like ours) that number is down to 0.1% and halving every 8 days. The probability of another player having Coronavirus is 1 in 100. The probability of it transmitting to anyone during a game of cricket is described as "very remote" by leading experts.
Multiple "very remote" by "1 in 100", and you have a very, very, very safe activity.
