The passing numbers are going to lie to you on this one. Hundley looked bad. Their 3rd down percentage was atrocious, and the only passing plays that were working for UCLA were little bootlegs and WR screens. And despite those plays working all day, they got away from them in short yardage situations, resulting in a handfull of field goals instead of TDs, as well as at least one 4th and 1 fail (when the defense wasn't even set yet!). The bright spots here were Paul Perkins at RB and the WR corps for UCLA, all of which had huge yards after contact.
Hundley's big plays of this game were all made by the receivers, not by his passes, and Hundley's fumbles were awful (one by running into his own man). His interception was a bad pass which - had it been on target - would have resulted in a big gain for 1st down, but instead was thrown behind the receiver right into the arms of the trailing defender. One bright spot here: Hundley got rid of the ball faster and took fewer sacks, but that may be more the result of Cal's defensive plan than Hundley's growth.
