Mike Nolan has the 49ers on track for another fast finish in the regular season's final three games. It's those first 13 games that Nolan hasn't figured out in three seasons with the club -- and the coach knows that's why his job could be in jeopardy despite the 49ers' knack for big endings. "I'd like to hear people say that year in and year out, 'They play well in December -- along with September, October, November,"' Nolan said Monday. Not this year.
