I am spit-balling here, and I don't think that this should happen but...
What if during the offseason Mark A/GM to be named later decides that they have the lineup to contend? They have Fielder and Hart under control for another year, and have the lineup to make a run. They know that they don't have a starter besides Gallardo and maybe Wolf. That leaves them with 3 open spots in the rotation, which is very hard to overcome, but Cliff Lee is a free agent and they might be able to pick up an arm via trade: something like Lawrie and Gomez for a young-ish, MLB ready pitcher that slots as a number 3/4 starter. (Again I don't like this for the organization, but I could see it happening.)
At that point the "traditional" lineup looks like:
3/4 New Guy
5. Loe/Parra/Narve Dog
Closer: The Ax Man
Setup roles: Hawkins/Braddock
LOOGY: Stetter? - Haven't heard how he is doing in AAA
Middle Relief: Parra/Loe/Narveson, Villanueva, Jeffress(?)
Backup Catcher: One of the AAA guys.
MI: Someone Cheap
They have a ton of money coming off the books - and some arbitration eligible players. But if they are able to bring Lee in, they might be able to pull it off.
