Damon is Coming. What do you do?

I know I have alluded to what we should do when Johnny Damon and his left handed bat arrive in the lineup here and there.  However I thought now would be a great time to really analyze the best options.  There are two main factors as to how he will be used. 

1)  Are the Indians winning?
2)  How are the performances of Shelley Duncan and Grimmace? 

To answer the first, if the Indians are winning there will be very little desire to rock the boat and to make a move, just for the sake of making a move.  Manny Acta doesn't manage like that, he stays the course as long as that course is equating to wins.  If the Indians are winning in-spite of a struggling player or offense, that is completely different.  However, as long as the team is winning, you got to think the chemistry and law of averages will work out for the struggling players.  If the Indians are winning, then Damon will be used as a priority pinch hitter, and will spell Duncan, Choo, and Brantley(if he can convince the coaches he can play CF). 

For the second things get more intriguing.  If Shelley Duncan is struggling for a few weeks prior to Damon arriving, then you could see a platoon out in LF.  This works great when you factor in how good Shelley Duncan is at pinch hitting.  I am sure he doesn't like that label, but until he can establish himself as an everyday player, then teams will find the most value in him with that role.  However, if Shelley Duncan is hitting great, and Grimmace doesn't turn things around, that's where things are interesting.  How bad is the offense?  If the offense is still putting up huge numbers as they did on this past road trip, do you sacrifice the defense to put Damon in the lineup?  It's a lefty-lefty swap, because Shelley Duncan can play first base if you want to bench Grimmace.  Now Duncan is a huge step down in defensive ability at 1st from Grimmace, but he isn't the biggest liability in the world either, so do you sacrifice defense in hope for more runs?  This scenario in my opinion is the best scenario for the use of Damon, and then you gave Grimmace as a defensive specialist or trade bait.  Problem for this theory to come true?  The Indians will have to be losing AND the offense will need to be struggling.  I don't want that to be the case just to see Damon and Duncan both play everyday.  I will stick with Grimmace and his solid defense to keep the pitchers moving thru innings, and to keep getting wins any day over a few more hits.
