some stamina is useful, but not too much, because then you'd have a hard time managing minutes
stamina never reaches above prominent (10) and usually for my team the sweet spot is between 4-7 (inept-respectable)
at least for me, some other teams probably think of something else. Some stay low stamina (your range; 3-5) but it never hurts to train stamina, because too little stamina (1) causes players to under-perform in the 4th quarter of key games and cause more fouls.
