One of the downsides of the B1G - it is no secret - is the "beat each other up" syndrome. Presumably because teams are actually fairly even, but what happens is that the expected winner doesn't consistently win games.
You see some of this in the Big 12 as well, less common in the PAC and really not a factor in the SEC and ACC, where I would argue that - in a high percentage of games the expected winners, well, win.
When the expected winner usually wins it is bad for the not so good teams, but very good for the better teams, as their RPI and record look better for the NCAA seedings. Not so good in the B1G as there are so many teams with middling records, just a couple good and of course a couple really bad. Hopefully, RU among the good, of course.
