GRR: California
Before he became a hall-of-fame coach, Jack Clark was an outstanding player.
Clark played football and rugby at Cal in the 1970s and parlayed a great size and athleticism, along with an analytical mind and desire to understand all aspects of the game, into his becoming a top-notch international player.
Loren Hawley was widely considered one of the very best rugby players to suit up for Cal.
An openside flanker who was dominant in the lineout and athletic and physical all over the field, Hawley probably could have played anywhere from lock to flanker to No. 8 to center and still have an enormous impact on the game.
Ed "Mush" Graff was a Cal rugby player in the early part of the 20th Century.
It's kind of astounding that Mike MacDonald was a capped Eagle prop at 20, and while that has happened since, it's still a massive accomplishment.
Rck Bailey was the starting prop for the USA through the 1987 Rugby World Cup.
