Telling the PF to "put it down" (during a long hold-off) is asking for trouble. That can lead to "spiking" the aircraft nose-wheel first and a bounce is the likely result. It is usually a nervous captain saying "put it down" as I can not visualise a first officer demanding that if the captain is landing.
I found many pilots were not advised how to 'put it down'. If it became necessary it was often caused by too much back elevator; thus the answer was to relax the nose and land flat; or worse. The other danger is pulling back even more. My technique, if tending to float a couple of feet above the tarmac, was to 'drop a wing', remembering of course where the wind was. Immediately a main wheel touches down the speed brakes deploy and the a/c sits down.
It's a simple technique, it works, and is not emphasised; but I used to teach it.
