The puzzle isn't getting to the playoffs. It is doing something when you get there. The Tigers DO NOT have a offense that can generate runs by working the count and wearing down the opposing pitchers. This is a bigger issue than have one more relief pitcher, who might make 1-2 win difference over the course of the season.
Lack of late inning offense has cost us the double amount of wins, as the relief pitching.
Okay, so how does a long term solution at SS and 2B help you do things once you get there? We already have MI starters.
