Turnarounds are usually accompanied by tall tales.

Struggle one season but flourish the next? Odds are the reasons for the turnaround come with a large dose of intrigue.

Unless you're JaVale McGee.

His success 10 days into Nuggets training camp has been a complete turnaround from last season but there is no elaborate explanation. There's been no epiphany. McGee said there's been no drastic alteration in how he goes about his work.

It's all as simple to him as basic math — opportunity plus positivity equals productivity.

"It's not really a different mind-set" McGee said. "It's just no preconceived notions of what I'm supposed to be or what (new Nuggets coach Brian Shaw) wants me to be. So it's definitely all positivity coming into training camp. He sees everybody is working hard and we are all getting the same opportunity."

Last year training camp was where McGee lost a chance at being the Nuggets' starting center even though the 7-footer signed a four-year $44 million contract a couple of months earlier. This year even though he's been expected to start at center ever since Shaw was named coach he's earning the job through improved production.

That was evident in the Nuggets' first two exhibition games against the Los Angeles Lakers this week. McGee averaged 22 minutes 13 points and seven rebounds. He shot 47.4 percent from the field and made 8-of-8 free throws.

"It was real positive" McGee said. "I was working hard just working on my game and I felt like I did a good job."

A season ago McGee was asked to fit a role as a shot blocker. He was restricted in a way that he hasn't been under Shaw. McGee has returned the faith shown in him by being more serious about his craft.
