Just read the CVR transcript.
I agree, the pilots sound just like any pro's would sound. They were clearly aware of the runway state (i.e. slippery) and aware of the thrust reverser inop. Furthermore, going under the GS makes perfect sense.
The CVR transcript also has "RETARD, RETARD, RETARD" in it. This means that the thrust lever(s) were not idle, causing the autobrakes to disarm upon touchdown, and the spoilers to remain retracted. (computer logic) Therefore no weight-on-wheels while braking!!
-The approach was stabilized, no rushed approach.
-There was no time for the crew to realize what was going on...
