I liked to leave my kicker open so people can see it. Sophomore he was at 66% and it only got better. I think some balance and speed help. Try to level him up with all accuracy and less power, asking your coordinator to keep ranges shorter until a few seasons worth of SP. That way you can concentrate on accuracy and consistency only, rather than all 3.
