As he sat along the scorer’s table, Warriors coach Steve Kerr surveyed a roster that bears very few question marks. The Warriors have the best outside shooters in Stephen Curry and Klay Thompson, boast one of the biggest stars in Kevin Durant and feature one of the top defenders in Draymond Green. So even if the Warriors (2-2) enter Wednesday’s game against Toronto (2-1) at Oracle Arena with some inconsistency, their roster provides clear answers on their trajectory. Well, except for one. Who will become the Warriors’ backup shooting guard? “It hasn’t crystalized at all for me,” Kerr said. Kerr has two candidates from which to choose. After the Warriors gave $2.4 million to the Milwaukee Bucks to select Patrick McCaw with the 38th pick of the 2016 NBA draft, he became a promising rookie capable of starting in spot minutes and coming off the bench on extended playing time. McCaw, who turns 22 on Wednesday, has averaged 1.3 points on 40 percent shooting in 12.7 minutes off the bench in three games. Instead of focusing on those numbers, the Warriors remain intrigued with McCaw’s offensive and defensive versatility. “Playing or not, that has never affected me as a basketball player,” McCaw said. “I know that one day, whether it’s tomorrow or 10 years from now, I want to still be in the NBA and still be playing. I know if I continue to do the things I’m supposed to do right now at this age, it’ll work out.” This past summer, the Warriors signed 32-year-old wingman Nick Young to a one-year deal at their $5.2 mid-level exception in hopes to boost their secondary scoring. Though Young arrived to training camp with questionable conditioning and shooting inconsistency, that has not stopped him from averaging 9.8 points on 59.1 percent shooting in 15.5 minutes per game off the bench.
