Last season, the Dodgers used 16 different starting pitchers. That was the most in baseball, but no team used fewer than eight starters. Everyone wants a stacked rotation, but throughout a long regular season, depth is just as important as star power.
The Dodgers, with injury question marks in three of their six starting pitchers, especially need solid pitching depth. Signing bounceback candidates to low cost contracts should be something this FO does a lot of. Last year they threw out a lot of these offers, and Mike Bolsinger was the only one that really stuck.
