Stanford football has dominated the Bay Area college sports scene for the better part of seven weeks, what with the Orange Bowl invite and the Heisman and the Orange Bowl game and Andrew Luck’s decision to stick around and Jim Harbaugh’s decision to leave and David Shaw’s promotion. But across the Bay, and away from the spotlight, Cal football is having an extremely productive winter. Yes, the Bears lost star tailback Shane Vereen to the NFL Draft, and that’s a big blow, for sure. But it wasn’t a surprise — Vereen had graduated, after all — and it doesn’t by any stretch overshadow the positive developments in Berkeley. I’m referring, of course, to the coaching staff upgrades and the recruiting successes, which border on the phenomenal considering the won-loss record in 2010.
