Joel Freeland as the primary backup to starter
Robin Lopez. He saw action in 29 fewer games in
2013–14, with his minutes and points per game cut in half, as the Blazers transformed from a lottery team to a playoff contender. On January 2, 2014, he had a season-best game with 8 points and 10 rebounds in a 134–104 win over the
Charlotte Bobcats. In
2014–15, Leonard played only 13 total minutes in Portland's first 9 games as he was stuck in the big-man rotation behind Lopez, Freeland and

Brooklyn Nets, Leonard picked up the start at power forward, playing 29 minutes.
