just out of interest, why do you think the wonderlic is administered to potential draft choices? is intelligence not part of personality and thus a psychological measure? read a bit about the vetting of jamarcus russell. he and his familty were interviewed extensively before the draft. i'd expect those interviews weren't done by guys moonlighting from their dishwasher jobs. after that disaster, you can bet that there's plenty more psychological evaluation going on pre draft. when maturity is questioned before a draft, who do you think is doing the evaluation? my point is that whomever is doing it isn't producing very reliable results. if sports psychology were as valuable you seem to believe, this wouldn't be the case. you may conversely want to ask yourself why you are so convinced of a relatively new disciplines value.
