The next three weeks will go a along way toward determining the future of the program. Most everyone thought we'd get to this point of the season with M at 4-1 or 5-0. Over the next three, if M goes 2-1 or 3-0 it will almost certainly be viewed as a successful season and the RR era will definitely be exanded. It think going 0-3 would likely mean the end of the RR era as most likely the team would end up between 5-7 and 7-5 inclusive, but would have gone 1-7 to 3-5 in the Big Ten and ended the year with a 0-7 or 2-5 record over the last seven games. That is simply not good enough.
If M goes 1-2 over the next three, that marks a middle ground and the future of the RR era will depend on the performance over the last four games. Given how well the offense has performed, unless the wheels come off in the final four games I think this will be good enough to continue the RR era.
