Heralded as an All-America at USC, he proved his worth immediately as a 49er rookie in 1981. His statistics are not as numerous only because they do not catalogue the ferocity of his hundreds, maybe thousands of tackles. He was at the forefront of the 49er resurgence in the '80's, noted as one of the most intelligent, most courageous cornerbacks/safeties in the NFL. He was seven times All-Pro and selected nine times to the Pro Bowl. Enshrined in the Bay Area Sports Hall of Fame in 1999.
