Too early into using the Special Abilities, but you can salvage him although others would likely say to retire him. Get Throwing up to a natural 67 and both vision to natural 48. Then, as a general on the field, focus on building his vision and throwing relatively evenly. Some say a ratio of 1:1 works, others a little heavier on throwing. Just see with what works. I'm just going on what else I've read about QBs.
Hope that helps until someone a little more experience can give you an answer.
