There are things you can do.The biggest impediment right now to the OC going at the same time as Ventura is the mask order. While the OC is not as extreme as the LA County order, it does require masks any time you can't ensure the 6 ft distance, even if outside such as on the beach. The OC sheriff has said they aren't going to enforce, but will educate, but that's still going to stop parks and rec, insurance providers, and Cal south from giving the greenlight without clarification on what's required. The good news is the OC Supervisors are drilling down on it, trying to get to a policy that makes sense. The bad news is its politics and so will take time....that piece has to be clarified before the greenlight is given and hopefully it comes together soon. At least initially, it might require 6ft distancing between players in training such as individual squares, which I can't see lasting very long (some teams will cheat, pressuring other teams to cheat too).
All the cone work is fine. Trapping and crossing drills work. Most passing drills work, though maybe not rondos. Obstacle courses are still fun. Cloth masks are ok on cool days.
It is not ideal, but masks and distance would be better than no practice.
Just dont break all the rules and make them yank everyone's field permits.
