It makes no sense, unless he has also some JS. And even then without enough IS he will miss layups.
If it sheds any light on the matter (well, even if it doesn't), the two guys I'm talking about are both guards and are only in the low 40s on OD+ID+SB, so it's the JR part of that which brings them close to 60 (though guards with 15 SB are kind of rare too, I think).
