I'd do it.
If they posted that as CFFB WOD, I would do it - just not at those weights. I can't clean that much for reps. It looks like a brutal workout. I don't play football so I have no opinion of the carryover, except that you have some serious work capacity if you can giterdun. I would also allow ample recovery time after this WOD, and eat like a pig.
What do you mean let's listen to "Viking metal"? Vikings didn't play heavy metal, they played bongos and flutes!
