May is almost certainly too aggressive, if for no other reason than you need to have a reduced ramp up spring training, but I don't think it's that unreasonable an idea. You eliminate the risk of travel, and while yes there are non-players that would need to work to support this, we're almost as close to June as we are to Valentine's Day, and by that point on the current trajectory it doesn't appear to be a hyper-dangerous proposition. Certainly possible that circumstances change, but they need to start planning now for whatever the season could look like.
