Andre Drummond is a great basketball player, but he might be the worst free-throw shooter in NBA history.That's not hyperbole, either. This season he set the single-season record for worst free-throw percentage (35.5) and now owns three of the five worst single-season free-throw percentages in the history of the league (he's Eric Hosmer Jersey played only four seasons). Oh, and if seasonal records aren't your thing, he also set the single-game record for mi sed free throws by Cory Spangenberg Jersey going 13for36 from the line against the Rockets in January.FEATURE: As noted, Drummond has struggled with free throws his entire career and he addre sed his woes on Twitter in 2013 saying he'd never shoot underhand.Let me make this clear.... I'm not shooting free throws underhand.. Andre Drummond (@AndreDrummondd) Well, his stance has apparentlychanged after more years of frustration. During the team's season wrap-up Thursday, head coach Stan Van Gundy said he spoke with Drummond, who is now considering anything to improve, including underhandfree throws.As far as shooting underhand or anything else, its fair to say my discu sion with Andre yesterday and the discu sions Jeff and I have had and staff everything is on the table, Van Gundy said, .It wont be a unilateral decision; well do some research Tony Gwynn Jersey 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 its an important thing Andre more than any of us hes pretty open to anything. Theres a lot of ways to Rollie Fingers Jersey attack this problem and well all have a hand in it.MORE: Drummond's poor free-throw shooting played a role in the Pistons' season and their playoff series against the Cavs. Yeah, they got swept, but the games were competitive, and Detroit might have been able to win a few more games if their All-Star center wasn't on the bench at the end of the fourth quarter.The 22-year-old is in line for a max contract this summer, so he's going to have to earn that money by playing well in all aspects of the game. If that Rickey Henderson Jersey means shooting underhand, it seems Drummond is willing to do that.
