The end of game possessions are on Sam but also the personnel. It's hard having Rubio and Dieng out there and not ISO Wiggins because on Pick and Rolls they can make one of those two guys take a shot. I'd still rather see that then them standing still and making Towns an offensive rebounder late in games. They got great looks throughout the game with movement and good passing and that kind of stops in the last 5 minutes of the game when it tightens up. The last Wiggins shot was real bad and if I remember right, I think Draymond Green was guarding him which makes the shot that much more difficult.
Lavine gets caught up in the moment too much which is explainable for his age and lack of experience and consistent playing time until the last month or two. But he's really gotta learn when to slow down and not try and get the crowd going with a flashy pass that doesn't need to be made or shooting long 2's and long 3's just because he feels like he's in a rhythm. Those shots fall and he isn't as aggressive trying to get to the rim unless it's a fast break.
I think the next coach, and pray to god it's next year, will know KAT is the franchise player and best offensive player on the team and he needs the ball to close games out.
