Off-season means time for things that matter, like training, eating, sleeping... around, and such activities. What sort of training you might ask, well. Depends on what you need to work on, Mephi spends loads of time in the church of satan. Where he prays to his father, to Baphomet, to the unholy spirit. He eats mostly goats, not because they taste the best but because they have the best-looking skulls and he collects them, like a normal person.
Sleeping is best done while on cocaine, it's quite similar to how a TV pastor would relax but much less begging for money and guilt-tripping uneducated souls.

Once the season approaches it's important to cut out the cocaine, it's not good to have it in the system in case of random drug tests during the games.

The offseason can be a drag, but hey. It's what you make it, and make sure you make it good.
