The Warriors seemingly have everything they could want in a roster. The Warriors have four All-Star players in Stephen Curry, Kevin Durant, Klay Thompson and Draymond Green. The Warriors have arguably the best shooting backcourt of all time in Curry and Thompson. The Warriors (23-6) have the kind of depth and team-oriented structure that has helped them absorb overlapping injuries to Curry and Green and secure eight consecutive wins entering Monday’s game against the Los Angeles Lakers (10-17). In what represents the ultimate NBA first-world problem, the Warriors roster has given coach Steve Kerr a challenge on fulfilling his desire to play everyone on his 15-man lineup. And lately, JaVale McGee has become the latest casualty, averaging only 9.5 minutes in the past five games in what has consisted of a healthy scratch in one game and mop-up duty in two others. “The league is going so small and it’s getting faster and smaller seemingly by the day,” Kerr said after morning shootaround on Monday. “The old school 5 is almost becoming a dinosaur. As a five man you have to be able to cover 3 point shooters. You have to be able to cover point guards on dribbles and isos. It’s the job description that’s changing.” The Warriors have liked how McGee has filled his job description in the past two seasons as an energetic and athletic reserve center that can throw down dunks and make defensive stops at the rim. The Warriors would also like to see 7-foot-, 270-pound McGee to improve his perimeter defense.
