Andre Drummond appeared to have a thinner physique at a public appearance on Tuesday and understood his responsibilities heading into the summer.

"It's just a mentality," Drummond said. "I just have the mind-set right now that I don't think has been there before. I told myself this is a big summer for me. Obviously everybody knows it's my contract year, but it's not even because of that. I'm just so tired of losing that it comes down to me and what I'm doing on the floor and that if I'm not in the best condition, the best playing shape, I can't do nothing for my team.

"I'm willing to take this summer real seriously to really become a better leader and show everybody that I'm here to get the program where it needs to be."

Drummond is eligible for a contract extension in the offseason.
