I wouldn't say the West is down. I actually think the West is up. They just lacked a great team. But 1-6 was all pretty darn good, and Illinois had enough offense to be a pain when they were clicking.
Northwestern has had a good Big Ten season, but a bad non-conference season, which begs the question: is it better or the division is worse?
Purdue feels improved, but had the same record last season. It is on the better end of its decade-long performance, but that's a bad decade of football. Minnesota is one game better than last season, but well within a standard deviation of its mean in this century (I'm not sure that's technically accurate, but it's probably close). Illinois is hideous, but two games better than last season (4-8 is in the bottom half of the last decade, but better than the last two years). Nebraska is historically bad (same as last year), but apparently improving. That leaves Wisconsin and Iowa. Wisconsin had its worst regular season since 2008. And Iowa had a season that looks a lot like the last decade (Iowa has had 7 or 8 regular season wins every year since 2010, except when it won 12 in 2015 and 4 in 2012).
Oh--and Northwestern has a worse overall record than last season, and is only one game (Wisconsin) better in the conference.
So Purdue and Nebraska feel like they are getting better, but had the same record last season. Iowa feels worse, but is steady as she goes. Illinois and Minnesota have improved records from last year, but they are both going from bad to not quite as bad. Wisconsin is worse, and went from really, really good (4-straight 10+win seasons, 7 of the last 9) to thoroughly mediocre.
Overall, the only big change is Wisconsin, which is much worse than usual.
Unsurprising that a Wisconsin fan doesn't think the division is improving.
