Well, no one can say the Marlins don't have a type.
Just like, well everything else the Marlins have done this offseason, it's fine in and of itself.
The problem is if that's all they do.
Relying on Mondesi as anything more than organizational depth, or maybe a late inning defensive replacement and baserunning specialist, seems crazy given the track record. To borrow from another sport, Chris Grier would turn away from that kind of injury history.
