This past April, former GM Jim Bowden, who now writes for ESPN.com, surveyed current general managers about who they thought were the best future GMs, and Levine was at the top of the list.
"Levine has been the assistant GM of the Rangers for the past eight seasons and has assisted [GM] Jon Daniels in player acquisitions, roster composition, contract negotiations and statistical and financial analysis," Bowden wrote. "He has high character and has the endorsement of most GMs in baseball as next in line in the industry. Daniels is still in his 30s, so it's likely that he will have to go elsewhere to get a GM job."
Levine joins Allard Baird, Larry Beinfest, Billy Eppler, Gary LaRocque, Ray Montgomery, Hal Morris, Tim Purpura, Dave Stewart and De Jon Watson as the confirmed candidates.
D-backs chief baseball officer Tony La Russa has said he would like to have a GM in place by the end of the regular season.
