Passage: With Mustaine sober, Megadeth continued searching for a new lead guitarist. Among those auditioned were Lee Altus of Heathen and Eric Meyer of Dark Angel. Meyer was invited to join the band after Poland's departure, but chose to remain with Dark Angel. Guns N' Roses guitarist Slash had been jamming with Mustaine and Ellefson, and although it seemed that he might join Megadeth, he remained with Guns N' Roses. Dimebag Darrell of Pantera was offered the job, but the deal fell through after Mustaine refused his request to recruit his brother, Pantera drummer Vinnie Paul, as he had already hired Menza. The offer was also extended to Criss Oliva who also declined as he did not want to leave Savatage. Jeff Loomis, who would later go on to form progressive metal titans Nevermore, also auditioned though Mustaine deemed him too young to join as Loomis was only 16 at the time.

Question: Why did Dimebag Darrell's deal to join the band fall through?
Mustaine refused his request to recruit his brother
