Genuine question because I know sometimes we go at it... But how do you know Pop and/or the coaching staff aren't teaching those guys how to play off the ball? There is an element of just knowing to do so when an opportunity presents it self from playing ball from young honestly.
But the other side is, I think it's showing Timmy's absence. When he caught the ball up at the key, (heck even David freakin' West, gotta give him props), they were good at making that pass to the cutter. Pau is good, but our other big guys, not so much. And LMA isn't drawing doubles to free up other guys, so it's tough to get cutters going down the middle of the lane because of the way LMA plays.
More than anything, it's probably a chemistry thing. TD could throw a pass backdoor and knew TP or Patty would be cutting just from a look they gave each other. GS essentially adopted our beautiful game offense, and it works because they've got the right personnel, chemistry, and spacing required. We don't quite have that anymore, so it just looks ugly at times. Much like our prime TD days when people called us boring because it was "4 Down" so much and that wasn't "sexy" ... Except it's Kawhi doing the 1 on 1 ownage of defenses. He's just lacking other viable/consistent options unfortunately.
