you're not gonna like this but...
I think you should reroll.. With a QB there's no point in NOT 3-capping throwing (that is, get it to 68 naturally) first.
If you're going for a dual threat pass/run QB then speed and agi are next.
If you dont wanna reroll, do the following:
Use SP to get throwing to 68 (3cap)
while training confidence + carrying
Use SP to get Vision to 68 (3cap)
train strength on normal and use shopping tokens to look for good AEQ (you will be mid-20s)
Use SP to get Strength to 62 (2cap)
train Confidence and Carrying
Then go for SAs, and train Confidence and Carrying until they're capped, then Stamina.
