 Poland quarreled with Mustaine, and was accused of selling band equipment to buy heroin.As a result, Samuelson and Poland were asked to leave Megadeth in 1987, with Behler becoming the band's full-time drummer.Poland was initially replaced by Jay Reynolds of Malice, but as the band began working on its next record, Reynolds was replaced by his guitar teacher, Jeff Young, when Megadeth was six weeks into the recording of its third album.
