From the NBA.com article that is in the above Nuggets' tweet, I thought this might be of interest, regarding how Monte struggled a bit in the playoffs:
The key for Morris entering his third season will be improving his fitness. The former Iowa State standout struggled in the postseason, which he attributed to the amount of games he played overall this season (96).
“Personally, I know I struggled in the playoffs but overall, with this being my first time going through this long season, for me to hit my walls when I did and get back from it, I didn't get too down on myself because I know I can play at this level,” Morris said at his end of the season availability.
He added, “Flexibility is going to be big for me this summer, working on my hip power, getting a lot faster, my mobility. On court I'll still be the same, grinding like I did last summer. But I'm going to focus more on my body more when it comes to movement, so I can be more durable down the stretch of the season."

NOTE: There's a 3+ - minute video in that article of Monte going back to Flint during the season (when they played the Pistons) that shows a lot about his character. One of his 7th-grade teachers showed up to see him at his autograph / photo session.
