SANTA CLARA, Calif. -- It would be unfair to pin the San Francisco 49ers' three losses on quarterback Colin Kaepernick.The entire offense has slumped together in the team's losses. But there is no doubt -- when Kaepernick plays well, the 49ers win; when he doesn't play well, the 49ers lose.Consider these numbers from ESPN Stats & Information:The 49ers are averaging 34.7 points in their six victories. They are averaging 6.3 points in their three losses.
