I'd suspect the 2 week hanging time had a lot to do with the bad meat. Unless you had it in a cooler with a constant temperature in the mid-30's.
I'm not a fan of washing down wild game with a hose. I don't know if that has anything to do with gamey meat, though. Possibly. I take a bucket of water with a couple wash cloths and soak/ring out then wipe off all blood and hair. When I process I remove the entire outer layer of "dry" skin before I begin deboning the quarter.
