Derrick Williams said his recent play reflects a change in mentality, particularly his focus on rebounding while filling in for the injured Kevin Love.

Williams has delivered double-doubles in three of his past six games, and is averaging 18.2 points and 10.2 rebounds during that stretch.

"Rebounding really is what got me going," Williams said. "Trying to get every rebound has got my confidence up, not really knocking down shots. I'm focused on the defensive end and trying to get as many rebounds as possible."

Williams was an unheralded prospect who played two seasons at Arizona and became the No. 2 pick in the 2011 draft.

Williams sees himself on the same trajectory in the NBA.

"Pretty much the same thing: Struggled my freshman year in college and sophomore year, I turned it around," Williams said. "I feel the same thing going on now. It really does stink that Kevin's out, but it really does help me with my confidence and trying to build it. It's tough playing behind an All-Star like that, but at the same time opportunities come around. This is the second time around that really helped my confidence a little more."
