What to do with Big Papi?

What should be done with our struggling DH? A guy that could have ended each and every game, seemingly, had he been given the opportunity just a few years back.

Now, he can't hit himself out of a paper bag. And I mean a bag that is already ripped in half, tearing down the middle.

He still has a pretty good approach--taking pitches, working the count. But more of that seems to due to the fact that he realizes his bat ain't what it used to be. So he compensates by being, or so it seems, just a little more passive.
