Runway excursion by DL MD-80

Runway Conditions

let's see ..... you shoot an approach to a snowy icy runway in low visibility, with a quartering tailwind, to a relatively short runway by airline standards, in a aircraft with twin tail mounted engines, and you are surprised when you weather vane the airplane off the runway when you apply reverse thrust? I would proffer that there was probably no problem with the brakes themselves, just the fact there was most likely little to no braking available due to runway conditions.
