All the answers above are right, and there are many more that are right depending on the situation.
Our younger son, 5-10 RHP, 85 mph in HS, pitched at a Power-5 school and left barely touching 90 but as the all-time innings-pitched leader at that school. "Spectacular command" is how one scout describes him (now pitching in double-A).
So when you say, "By other things i mostly meant control and off speed," I say, yeah, he has/had all of that. But your definition, mine and a college coach's may be different (I sure didn't know how to judge if he was good enough - in fact, I wouldn't let him commit for a while because I was so unsure).
In other words, they will make the judgement, no formal recipe within reasonable bounds - keep on pitching in front of people and they will decide.
