When Phil was the coach, he would immediately yank players out if they didn't play defense. The message is very clear to the players; if you don't play defense, you're not playing. In D'Antoni's system, players are not focusing on defense and it shows in the stats. The Lakers are ranked at the bottom of the list in defense this year. You don't even see urgency in the players when we are on a 3 game losing streak.
Like Magic says, if we don't improve our defense and start to win close games, we are not even going to make the playoffs. You may not like the message, but its the truth. If you don't like hearing the truth and pretend everything is going great, thank you for being a member of the Democratic Party.
