After a record-setting night of 3-pointers for Golden State, coach Steve Kerr's focus was more on deficiencies at the other end of the court that nearly cost his team a game against an undermanned opponent. Klay Thompson scored 40 points and Stephen Curry added 33 as the Splash Brothers combined for 14 3-pointers in all in a 128-120 victory Friday night over a Dallas Mavericks team missing Dirk Nowitzki and two other starters. Thompson and Curry made sure it didn't matter.
