If the Rockies are looking for a candidate who has “paid his dues”, Glenallen Hill would be a strong choice. Hill has been with the Rockies organization since 2003, and he’s been the manager for Colorado’s Triple-A team since 2013.
Colorado’s rookie class in 2016 was incredibly successful, and Hill deserves at least some of the credit for that. David Dahl specifically credited Hill for developing and preparing him for the Major Leagues. The Rockies roster in 2017 will be full of young players that played under Hill in the recent past, so there would be a level of comfort and continuity there as well.
