Whatever the ranking of a school, it is the experience as defense attorney that's critical. In any case, his advice is echoed by Supreme Court Justices and other attorneys - he's just more colorful and his lecture gained a certain amount of internet fame, which is why I linked to it here... it's not your typical "dry" legal lecture, so it's fun to watch. Regardless, there is not much argument that the advice itself is spot on - I have not seen anyone anywhere make a case for anything else.
