I just bought a 20 intel 16 cons 18 team player off of transfers and I think he has the great starting stats to be a great QB one day but I'm not sure where to start training him. He has:
Passing of 5
Stamina of 1
Vision of 1
Positioning of 1
I know vision and positioning shouldn't be the first things I train but should it be stamina first to around 12-15 (I have fitness coaches and fitness center fully upgraded) and then passing to 10ish then do positioning and vision?

6 foot 2 208 pounds

Yes I only have fitness coaches although they are at 20, and whatever bonuses a fully upgraded fitness center offers on top of that. What should I get stamina to before switching?

I'd train speed and strength until they cap. If they both don't cap until 16+ then you have a great middle linebacker on your hands, which is even harder to produce than a QB. By the time that is done, he'll be 18 or 19, and you'll hopefully have a training hall and all the coaches necessary to make the most of his other skills.

For the long term, you'd really want be looking at 4.5* talent for a QB.

You have to keep track of the training pts. With full fitness center and 20 fitness coach, it takes a maximum of 3 (19 or 20 teamwork) or 4 (18 or less teamwork) weeks to increase a fitness skill by 1 pt if you focus train on the skill. If he hasn't increased in that time, he's capped in that skill. Keep in mind he can increase faster than this sometimes.
