Ricky Rubio does not have a ton of "gravity" -- despite spending years working on his shot, he has yet to become reliable enough from 3-point range to force defenders to stick with him out there. Opposing point guards often go under his pick-and-rolls. Usually, his defender is willing to help off him and give him a few feet of space when he has the ball.
In the fourth quarter, with the Knicks up by 16, Jennings showed absolutely no respect for Rubio's jump shot. Rubio had the ball behind the 3-point line, and Jennings was all the way in the paint. When Rubio didn't try to make him pay immediately, Jennings lifted up his arms and dared him to shoot.
On one hand, this is objectively funny -- you just don't see this stuff often in the NBA. On the other, though, this it's a little sad. As someone who believes in Rubio's overall game, it's kind of a bummer to see him shy away from shooting in this situation. After the All-Star break last year, he made 36.9 percent of his 3-pointers. This season, he has made just 26.9 percent of them, and his confidence just isn't the same.
