Before the Marlins opted to have Dan Jennings move from the front office to the dugout, several internal options were considered. Jeff Conine, Andre Dawson, Tony Perez, and Mike Lowell were all mentioned as candidates to replace Mike Redmond, and according to Barry Jackson of The Miami Herald, the Marlins were open to re-hiring Leyland.
After Redmond was dismissed, Leyland and a handful of other external candidates were considered. But President of Baseball Operations Michael Hill told Jackson none of those candidates were favorites to land the job.
All of the managers Hill mentioned have a significant amount of notable baseball experience, which is notable because of Jennings' brief managerial resume. Jennings may be a placeholder until the Marlins are able to take the time to find a long-term clubhouse leader, however that may not come until the end of the season. Baker, Washington, and Gardenhire may not be as familiar with the organization, but Leyland's experience and success could have given him an advantage.
Although some feel his days as a major league manager are all but over, Leyland has not formally announced his retirement. After managing Miguel Cabrera in Detroit, he has the ability to create a consistent lineup around a power bat. Leyland was known for sometimes sticking with struggling players longer than other managers would, but such behavior could result in distinct respect from players. If the Marlins lacked "fire," as Giancarlo Stanton explained in April, perhaps Leyland's style would have resulted in hope and confidence.
More often than not, catchers have an advantage because of their experience calling games. Leyland has catching experience and ranks 14th all-time in games managed and 15th all-time in wins. He finished first or second in his division 11 times and has a notable amount of playoff experience, which some of the Marlins' previous managers have lacked.
Despite the fact he was not mentioned as a candidate, Bobby Valentine may have also been considered. The organization has been linked to him in the past although he may not have the desire to return to the dugout.
Jennings could finish the season as the Marlins' manager but the club could explore other options moving forward. Leyland may be among them considering he guided them to a title and has experience managing young teams.
