He did play well. Gibbs had a number of open looks when he got the ball outside the arc and almost never shot it. Others did the same. When they got the ball, they then started dribbling and looked to pass. SHOOT IT! Especially if you have any sort of percentage at all.
Gibbs needs to develop some NBA-range shooting, as should everyone who can shoot it. They don't guard that closely in college outside the arc. And for gosh sakes, everyone stop going to the hoop against bigger and better players and forcing up shots.
