Well, I wish Vitale the best.It happens pretty quick with older men. Bobby Knight about 5 or 6 years ago was really sharp as an analyst. People may not have liked his style, but you could tell the guy knew his game. In 1 or 2 years, he basically lost it. He just has a hard time concentrating and staying focused on the game, and his comments are disjointed now.
Perhaps for Dick its more of a quick fall physically rathen than mentally. He still seems to have joy for games, and seems as aware and focused as he was before.
