True. Assuming that nothing changes from previous form, the OPR and CCWM can be very good indicators of probable results. However, there is an implicit error function on the numbers (otherwise, they would be 100% in the absence of meaningful changes). In addition, any team that knows they are on the short end of the statistics and does not try for a change in their favor is doing themselves a disservice.
I suppose that what I am trying to lead to is that the OPR and CCWM numbers are very useful tools (we use them a lot), but they only indicate based on the assumption that nothing will change from previous matches.
