Regarding drives per game I’m sure Stevens is emphasizing this, but it also may be a natural progression in Brown’s and Tatum’s game (improved handles and added strength), Walker has always been a driver, and Hayward looking more and more like his Utah days.
It’s just great to have 4 guys that can score like this if 1 or 2 of them have an off night. Walker just seems to blend in much better than Irving, but it also helps to have Hayward closer to his normal self, and another year of development for Tatum and Brown.
