Physical traits are readily measurable and, barring injury or the inevitable ravages of time, can be relied upon to endure over time. Those who make draft choices tend therefore to rely upon them, probably to a fault. Intelligence and character are less readily measurable and more subject to change, particularly for guys just out of adolescence, but they are at least equally important. When Bill was good in the draft he was very, very good; and when he was bad, he was very, very bad. When he was good, he was very, very good, in large measure because he knew the value of intelligence and character ("Does he 'love football," and so on.).
To this point, there is reason for concern with respect to Jacas regarding both intelligence and character. First there was all that whatever-it-was around draft time, which might (might) indicate an issue re character. Now, he looks a little dumb out there on the field. This gives legitimate cause for concern, but it is early, and none of us, I suspect, would care to have had a final evaluation of our merits be made on the basis of the nonsense rattling around in our brain when we were 22, or whatever age he is.
