Ryan Flaherty played for the Atlanta Braves back in the 2018 season. He appeared in exactly half of the team's games that season (81) as a utility player.
Flaherty only played 8 years in the league but was a part of some good ball clubs between the Balitmore Orioles, Guardians and Braves. While he may not have been an every day player for most of his career, Flaherty was able to soak in quality baseball and learn from different situations.
He played for Buck Showalter, Brian Snitker and Terry Francona. These are three of the most successful managers in recent years. If Flaherty was able to learn a thing or two during his playing days from these guys, he very well could make a quality manager himself.
