That article says nothing about "commited" versus "uncommited". It just predicts where they end up.
Since they don't reveal their picks until the 25th of January, you can probably take all of the recruits that commited at their words that they will go where they pledged they would and, even though you would tank on Joe McKnight for instance, you can probably get close to 70% accuracy on that alone.
If they were making these superaccurate predictions in early December, that would be an eye opener. But a week before signing day? Not so much.
Peytonknows was right. I would wager that, if this board collectively made predictions on January 24th (a day before those economists make theirs), the collective wisdom would get within 5 percentage points of theirs...and would probably even edge them out.
