Brill Walton's celebrity is no longer confined to the sports pages, but here his ""controversial"" life style and peripheral involvement in the Patty Hearst case become just another tag for a routine career bio. in any case the angle is none too flattering: Stambler seems to go along with Coach Wooden's opinion that Walton is ""no leader,"" just a victim of whoever talks to him last. Stambler ends lamely, with Walton looking forward to the '76-'76 season, and will leave his readers sadly deflated by the interpretation, true or not, that Walton is just another dumb jock. Boring.
