I would suggest retiring him and starting over unless you can find a team, because it is pretty hard to get a team for a level 10 QB. But if you want to keep him going I'd say get vision to 48, then throwing to 60, while working strength and confidence up to around 40, so you can eventually pump some sp there to the soft cap.
If you decide to start over (you'll get the flex) back, try working Throwing to 60, vision to 48 to start, and don't invest in SAs until at least level 20.
