Glue Guy

I would define "glue guy" a little different than the article does. I think the glue guy is a leader that keeps the team performing at it's highest level and yet doesn't need to dominate the scoring. They are the ones their teammates and coaches want to have on the floor, especially when it matters most.
Thus I picked Barnes.
About Barnes:
“Pop trusts him,” said USA assistant Steve Kerr to The Athletic. “Pop talks about it all the time with our staff. He knows he can count on him to make the right play and to execute under pressure.” (Yahoo Sports)
