We don't know how things will play out, of course, but on a logistical level, I think football is one of the easier sports to ramp up and play.
It has the biggest roster/bench of all the major sports and it's the easiest sport to feasibly make substitutions whenever you please, so the concept of "game shape" is very fluid.
It's also the sport with the most days between games, for recovery purposes.
Then again, those advantages depend on teams and players not being too hard-headed or stupid to avail themselves of the benefits of reduced snap counts and recovery days.
Baseball is the sport facing the most logistical headaches, I think, with special attention needing to be paid to making sure pitchers arms are properly worked up. If they get cute rushing the prep time, teams whose manager and pitching coach aren't wise about how hard to push pitchers are gonna ruin some guys' arms and possibly de-rail a few careers. And on top of the unique pitching arm issues, they're the sport with the most densely packed schedule so it's a real grind with constant travel and rare days off.
I read a piece talking to Braves' old pitching coach, Leo Mazzone, about the special attention he had to pay to this stuff when he managed the workload for his pitchers in a shortened, delayed baseball season and it makes you realize how much thought good coaches and teams will put into this stuff. Which of course makes you think about how little thought the worse coaches and teams will put into it, at their own peril.
