"I’m happy to be part of that situation," Jack, 28, said in a phone interview. "They traded for Andrew (Bogut). They drafted Harrison Barnes. Klay Thompson was the second-best rookie last year. It definitely looks like they’re serious about winning. I think we can make some noise." "I didn’t know I was a combo guard until I came into this league," Jack said. "I just play hard. People know my M.O. As long as I’m on the court, I’m cool. I’m going to do whatever it takes."
