But he's a ****ing alcoholic manchild that doesn't know how to take care of himself. Basically Tafo's Mango's babysitter. What a charismatic piece of ****
lol what are you talking about. Mango's gotten a lot more mature in his approach to the game over the years. Besides, it doesn't hurt to have a friend who's there for you and who deals with everything else so that you only need to focus on the game.
Tafo can essentially deal with all exterior things like travel, food, etc and yes, probably managing alcohol, while being another eye to help Mango in researching players and noting their habits.
I'd assume it's a "coach" like any physical sports athlete. Obviously the coach won't be better than the player and will most likely leave him to come up with whatever crazy ideas he wants, just there to fix quick things like getting punished for bad habits, coming up with quick responses to opponent habits, etc.
