A key and often necessary component of a rebuilding professional sports team is cutting costs. For example, we can say with relative certainty that at least four National League clubs are in some form of a rebuild — the Reds, Braves, Brewers, and Phillies. Via USA Today, those four teams rank 22nd (Reds), 25th (Phillies), 28th (Brewers), and 29th (Braves) in 2016 payroll.
Rebuilding teams typically rely on reclamation projects or cheap alternatives to fix glaring weaknesses rather than doling out cash to fix said weakness by more reliable means. Why spend the money to repair a problem when your philosophy is geared toward the development of your cheap, younger players and pushes the importance of wins and losses toward the back burner?
