Knicks’ Andre Drummond tells The Post how he flipped the script on his free throw woes

Before there was Hack-a-Mitch, there was Hack-a-Drummond. 

Unlike the former Knicks backup center, the new one solved his free-throw problem. 

Andre Drummond is coming off his 14th NBA season and the best of his career from the charity stripe. 

A free-throw percentage that started at 37.1 percent as a rookie and dipped to as low as 35.5 percent in his first All-Star campaign with Detroit reached a peak 63.1 percent last season with the 76ers.
