Well I'm not sure if you can get points to build his skills with a CAF from the create a fighter instead of through career mode. Easy to keep ur stats up just spar put one on each skill instead of putting all into one or 2 skills and same with training. train say cardio,spar putting one skill point on each skill,train speed,spar 1 point on each again,train streangth,spar 1 point on each again, so on and so on till you reach the safe zones of 30,50,70. At level 1 get every thing to 30 and you won't decay,level 2 get them up to 50,level 3 get them to 70. Remember no higher and no lower or they will decay. Then you can get into getting new moves and spar but save the points don't use them till the end and you will be able to come out with a good built CAF..
