HAWAII SENDS CAL (0-2) REELING AFTER BARR TAKES HIT, OFFENSE DRAWS BLANK By RON BERGMAN Mercury News Staff Writer BERKELEY -- Cal scored on its second series Saturday. On its third series, scrambling quarterback Dave Barr fell backward when tackled and hit his head on the artificial turf of Memorial Stadium. Everything went to black. By the time everyone woke up, the Hawaii Rainbows, 15-point underdogs, had humiliated the Bears 21-7. ''Dave was having problems getting signals after he took that shot to the head,'' said offensive coordinator Denny Schuler. ''On his short drops, he was hesitant and out of sync.'' Barr, who didn't miss a play, dismissed the first-quarter incident and went on to complete 25 of 42 passes for 277 yards. He did admit, ''I've never hit my head as hard as that.'' And then he found some humor in the wreckage of Cal's 0-2 start. ''The only thing positive,'' Barr said, ''is no one died in that game.'' No literal deaths, anyway. But Cal, which seemed so promising following four straight victories at the end of last season, including an Alamo Bowl win, sure hasn't shown any signs of life. And it didn't take a clergyman to pronounce last rites for the offense Saturday. Barr was sacked eight times for minus-43 yards. Five different receivers combined for six dropped passes. The running game sputtered to 83 yards, not counting the sacks. Fullback Marshall Foran didn't carry the ball at all. Yet the special teams made the offense look as if it was being operated by Joe Montana. Hawaii (2-1) ran two blocked punts in for touchdowns, giving sophomore kicker/punter Ryan Longwell no chance on the longest day of his short career. Longwell had no excuses for his fouled place-kicks, however. He missed both field goals he tried, one wide left from 25 yards in the third quarter, the other wide right from 37 yards later in the period. That's three misses in a row for the heir apparent to Doug Brien, who had three misses all last season. And just to rub the Bears' noses in it during their home opener, Hawaii quarterback Rodney Glover sealed the deal with a 1-yard keeper into the end zone with 5 minutes, 10 seconds left. Glover, who replaced ineffective starter Glenn Freitas in the second quarter, went to Riordan High School in San Francisco. He was recruited by Cal, but not as a quarterback. ''It's always been a dream of mine to beat Cal here,'' said Glover, ''because they didn't recruit me as a quarterback, but as a defensive back. I wanted to be a Cal Bear all my life, I guess, but they wanted to change my position.'' Cal was without inside linebacker Jerrott Willard, its best defensive player, who's nursing a sore knee. He really wasn't missed against the Rainbows' one-dimensional triple-option offense. This one wasn't the defense's fault. ''I've never lost a game before when the defense gave up only seven points,'' Cal Coach Keith Gilbertson said. Tailback Reynard Rutherford scored Cal's only touchdown on a 1-yard run with 2:32 to go in the first quarter. Little did the 41,000 (estimated) fans realize that was to be the extent of it for the Bears. Longwell got off a 55-yard punt on Cal's first series of the second quarter. But the Bears were caught holding Matthew Harding, who weighs all of 149 pounds. That made it fourth-and-47 from the 26 for the Bears, who had absorbed a 20-yard holding penalty two plays earlier. On the re-punt, Harding burst through the left side of the line and blocked the kick, the seventh block of his career. The ball bounced to teammate Khary Williams on the 20, and he ran it in untouched for the tying touchdown. Longwell's first punt of the second half, from the Bears' 46, was blocked by Robby Blakeney, who came up the middle without anyone laying a finger on him. Blakeney tipped the ball in the air toward the goal after it bounced off the turf, and Harding picked it up at the 16-yard line. No one touched Harding, either, and it was 14-7 Hawaii. Glover's coup de grace was a 51-yard run that set up his fourth-quarter touchdown. He started left, then cut right to a wide-open field. Jerod Cherry caught him at the 1, but it was too late to prevent Cal's second straight loss to a Western Athletic Conference team.
