Belichick makes the best decisions with the information he has available for him. He can't be everywhere at once, he has to believe the info he gets is reliable. Belichick has gotten bad info in the past that he has acted upon. In his book, Holley clearly states that in 2006 Belichick made draft picks against the objections of all of his national scouts, just because McDaniels said that his brother said someone was good. Something was clearly not right in that war room decision, and I find it hard to believe it was simply Josh McDaniels passively "giving his opinion" that caused BB to basically give his own national scouts a slap in the face.
