The down side of the regular season has begun for Colorado big-schoolers.

League play is here for Week 6, a veritable Phase II of the season.

For the next five rounds, there will be shifting in what is now the second year of a two-year outlay – and with another on the way for the 2020 and 2021 seasons – although qualifying for the RPI format remains the thing.

There is plenty of time for a move and plenty of games marked below for your viewing pleasure:
