Spiller just frustrates me, and I think it's more an intelligence issue than an ability issue.
What was his wonderlic score? I think I heard single digits. I know it was mentioned as one the all time lows. I know this doesn't sound nice, nor is it politically correct, but it seems to me that lack of ability to make a quick decision hurts him (I know, there are many exceptions to this theory; for example, I'm sure Trent Edwards had a much higher score than CJ and he seemed to have the same issue--but I would add, that there are many poster here on TBD who will point to the concussion game in Arizona and say he was never the same, and I tend to agree with that perspective).
Back to Spiller: I think it shows when he is running, he seems to lack that mental acuemn to make an instant assessment and decision to hit the hole and go forward, or to try an alternative route (which he usually does, to the outside, and other than the TD yesterday, it seems to always be the wrong decision).
If you've ever read the book Blink by Malcolm Gladwell, he explores this theory of mental process in a very engaging way. And I can't help but see applications to Spiller. The subtitle of the book is: "The Power of Thinking Without Thinking." Isn't that exactly what great players do? They make quick, instinctive decisions, and go without hesitation. Gladwell talks about and gives many good examples of how indecision causes so many problems in situations that call for quick mental process (like police work). I have to think playing football at it's highest level is a place where instant/instinctive decisions are called for on every play.
Well, I hope he does get it one of these days. There is no doubt he has the physical tools, but he just hasn't put it together yet. But as a huge Bills fan, I really hope he does.
