Minor League success in win-loss is definitely not equal to player development success, but it is interesting to note that the Rangers affiliates had the best combined record of all 30 teams under Matt Blood's season as director of Player Development.
Also worth noting is that this is what Rangers GM Jon Daniels said about Blood when he was moved from Director of Player Development to Director of Baseball Innovation. "...Matt's done a great job recruiting and added a lot of development tools for us, but the challenge of doing that and managing what is essentially our biggest department is huge. This puts Matt in a spot where he can identify the best practices around the industry and help us recruit the best people."
Mike Elias had this to say about Blood's hiring. “Matt has an unrivaled network when it comes to identifying up-and-coming coaching talent, and his knowledge of the latest trends in the player development sphere will help to keep us on the forefront of this critical area,”
So basically, what Elias likes about him jives with what Daniels deems his best qualities. If you can read anything negative from the reassignment with the Rangers, it is that perhaps he had difficulty juggling the day-to-day of running the minor league system. Which makes him a good fit for the Orioles job since Kent Qualls is by all accounts excellent at managing minor league operations, freeing Blood to do what he does best, namely recruiting and hiring top development-minded coaches and implementing cutting-edge technologies for player development.
