Detroit Pistons center Andre Drummond is willing to consider a throwback free throw style to improve a glaring hole in his game, according to coach Stan Van Gundy.

"As far as shooting underhand or anything else, it's fair to say my discussion with Andre yesterday and the discussions [general manager] Jeff [Bower] and I have had and staff -- everything is on the table," Van Gundy said Thursday, according to The Detroit News.

Drummond shot 35.5 percent from the free throw line this season, a career-worst average, while going to the line a career-high 7.2 times per game. It was the worst free throw shooting season in NBA history.

The first-time All-Star in 2015-16 often spent the end of games on the bench, as his poor free throw shooting make him a detriment to the Pistons in clutch situations as teams targeted him for hacking fouls.

So the Pistons will look at all options to improve Drummond's free throw shooting and make him a viable threat at the end of games.

"It won't be a unilateral decision," Van Gundy said. "We'll do some research on some things and come up with what we think is a good approach, talk to Andre and see what he thinks and develop an approach going forward.

"We all know it's an important thing -- Andre more than any of us -- he's pretty open to anything. There's a lot of ways to attack this problem, and we'll all have a hand in it."

Part of the problem is taking practice success into games. Drummond says he shoots free throws "really good" outside of games, and Van Gundy estimates that his practice conversion rate is 65 percent.

"It's just hard, for whatever reason, to translate from the practice floor to the game," Van Gundy told ESPN's Tom Haberstroh. "Look, you're standing there by yourself, with the game stopped, and everybody's watching. Let's say a guy misses a jump shot. The play goes to the other end, and everyone's focused on what's happening there. But Andre's standing there at the free throw line, all everybody's talking about who's watching the game is his free throw shooting. It's hard. It's really hard."
