If player 2 is going to be a PF train OD till player 2 gets a pop. Go with ID training after that and IS. When they are at a decent level (strong) train JS till average or respectable. Player 2 will need some one on one to get Handling up so do it for forwards so IS gets trained.
Remember to get player 2 some pops in stamina. Any 2 game weeks train stamina
