Top seeds in both East, West in trouble trailing semis 2-1

First-year coach Steve Kerr knows a crucial moment in the playoffs, so he understands exactly the test his Golden State Warriors face trailing Memphis 2-1 in their Western Conference semifinal. If his Warriors adapt and correct their mistakes mid-series, then the team that posted the NBA's best record in the regular season can continue its dream season. ''This is that moment for us, so we'll see how we respond,'' Kerr said Sunday, a day after the Warriors dropped their second straight with a 99-89 loss in Game 3. The Atlanta Hawks find themselves in the same spot as the Warriors, and these No. 1 seeds have become the first to trail 1-2 in a conference semifinal since the NBA went to the current playoff format in 1984.
