Generally i agree that SF tend to be guards without OD, but with A+ i would gamble for them since a good JS isn't enough to bring him into this salry and i would expect a good chanche to get a player who can several things good.
Even when i agree, hight would be the best measurement and then i tend to combine it like kr1shna a high potential player needs lot of secondary but i prefer to train primary more since they are easier so go with the 1.80 C to learn him how to play like a guard.
