Why have the Brewers been hyping Escobar so much?
Here's my theory: If the Brewers are going to need to trade for anyone in June/July it's going to probably be a starting pitcher, which will most likely involve losing a decent position player or outfielder.
With Hardy being the closest to Free Agency, and assuming Escobar continues to hit well (though power would be nice). I could see the Brewers trading Hardy for a good starting pitcher this year.
On the other hand, Hardy seems a bit like the "Molitor" of the team (ie. good looking, good playing fan favorite type) so they might just keep him.
