In my view, if the PF did not brief the PM properly and state clear parameters to monitor during the approach (especially airspeed), then there is a share of responsibility for the PM to request those parameters so that both are on the same page. As stated, pilots are fallible and forgetting to state at which IAS you plan to fly the approach at may be a simple mistake - easily forgiven, however the PM should pick up on this missing information and request it. (I cannot remember if this was a factor in this accident and I cannot re-read the report and check right now. This is more of a response to what's quoted.)
Regardless, if a pilot is rated on type, then they should definitely know the airspeed limitations of that type and I would argue that minimum IFR speed is high on that list when you're hard IMC, so that either of them let the aircraft fall below V min IFR is not excusable because "pilots make mistakes", particularly when lives were lost as a result.
