Hi Bird, referring to You. Spoilers can not be used differentially at ground mode,so they are more or less just aerodynamic brakes. Drags,if you prefer. And thinking of MD 80,a needlepin where everything happens so far back in there,the whole concept must be thought and adjusted that way. The way i thought of it,was being balanced in the nose of a very delicate mass,bit like being a goose. And so it behaves also on landing,sometimes nice,sometimes not so. Braking actions .40-.30 may be better for personal landings,but as here,i think the guys got just trapped by the circumstances. 80,is no-one`s favourite to skate around with. In slippery runways,it sure is a handful to keep it straight,so i would not find any blame on them. Things just happen,unavoidables when you do something. Incidents,to avoid accidents.
