If you look back at the history of NCS, you will see the Coach Grant's teams (girls) won the first two possible section titles in 1974 and 1975. His teams also had similar success in track as well. The Tamalpais track is still named after him and he was still coaching in his 90s at Terra Linda. Thanks to Albany HS coach Craig Stern for forwarding the link. RIP Coach Grant.
