I kind of get what you're saying but don't go to the gym for a year and see what its like your first 2-3 months back. His camp is going to be mostly focused on losing fat and Garcia isn't going to want to work on strategy until dude is in decent shape. More than half the training camp goes by and its a recipe for disaster.
They do both, fitness and strategy, but not hard sparring. Ali used to only spar the last two weeks to get timing right. Their whole life has been boxing b.. Plus you heard what Garcia said, maidana is a sponge.
