Is it wrong to rub a fatty? ..... my wife and I could not ...

try with out the drip pan.. i would think it sitting in its own grease would soften it up .. also try putting a rub on it.. some guys roll em breadcrumbs etc. I usually roll mine in my rib rub or bills season all and toss it directly on the grate close to the fire.. cook for a couple hours pull it out and eat.

There really wasnt that much grease in the pan...but as I said it wouldnt have made that much more of a mess with the pork loin right beside it.
Maybe it needed more heat too. Ill try some rub on it next time as well.
