Andre Drummond is arguably coming off of his best NBA season.Averaging 15.0 points per game (his second-best professional mark), and career-highs in both rebounds (16.0), assists (3.0) and minutes (33.7), Drummond took a slight step forward and reaffirmed himself as a double-double machine.Overall, his 68 double-doubles ranked second in the NBA while he led the Association in rebounding by a wide margin. In fact, he averaged 0.8 more boards per game than DeAndre Jordan, who ranked second in that regard.However, Drummond is far from a complete player. One of the major knocks on his game has been his lack of offensive ability aside from high-percentage shots at or above the rim.Despite already spending six seasons with the Detroit Pistons, Drummond’s efficiency has taken a hit. For example, during his second season in 2013-2014, he shot 62.3 percent from the field and put up 13.5 points per game. Last season, he shot just 52.9 percent. Although his volume more-than-doubled compared to his sophomore season (and therefore his shooting percentage naturally took a hit), he was not a reliable source of points on a nightly basis.He did make one stride in particular last season, though. As a lifetime 42.1 percent free-throw shooter, he spent last summer altering his stroke and managed to convert 60.5 percent of his attempts at the charity stripe, up from an embarrassing mark of 38.6 percent the year before.

Another step forward

This summer, he set his sights on another improvement. And this time, it will require even more practice and refinement.

According to Kristian Winfield of SB Nation, Drummond has been taking hundreds of three-point shots every single day this summer.

It's worth mentioning that the three-point shot has never been a part of Drummond's arsenal. Last season, he shot 0-for-11 from deep. Over his six years in the league, he’s gone 5-for-30 (16.7 percent) from beyond the arc.

With Blake Griffin slated to take on a high-usage ball-handling role yet again, Drummond’s expanded offensive game could easily allow the Pistons to have the most dynamic frontcourt in the Eastern Conference. Since Drummond also took a major step forward from a facilitation perspective last season with a career-high assist mark, Detroit as a whole could benefit from another offensive dynamic from their max-contract center.

We will see if Drummond can fix his shot in time for the upcoming season. If he can expand his offensive game to the perimeter, he might become a never-before-seen player based on his elite athleticism and rebounding skills for his size.
