Well if I were you I would put all of the SP you have saved up in throwing right now, get that to around 72. Do that while intense training speed and agility to give you a few extra points here and there. By the time this is all done you can start putting SP into speed and agility, get it to the first or second cap IMO. After that work on vision and strength. I am also going to be building a scrambler. Looks more like a pure passer now, but he will run someday.
