Mizzou future scheduling is up in the air until the SEC decides if it's playing eight or nine conference games. Even then, MU has some future series with Power 5 teams already under contract with Kansas, Illinois and Colorado.
Nebraska has a Power 5 noncon opponent every through the late 2030s. Oklahoma, Tennessee, Arizona, Oklahoma State.
For Mizzou and Nebraska to ever put a season together, it won't happen for a couple decades or they'd both have to cancel some other series.
Matt Rhule is a strong hire. He knows how to run a program, how to build a program in disarray and build a winner. Mack Rhoades wanted to hire him at Mizzou when Pinkel retired but couldn't get him here.
