That said, not surprising. Driskell has never cared for Book since he wasn't in on him as a recruit. I've listened to him and read his stuff (used to be at BGI) long enough to learn how this works. He evaluates all the recruits and the guys he likes best as recruits he talks up their entire career, even when they've done nothing (eg Houston Griffith) and guys that he viewed as limited he always talks down (eg Book).
