The West should be fairly wide open and unpredictable in 2019.
The only team I believe has no shot to win the West is Illinois. Otherwise, up for grabs between Nebraska, Wisconsin, Northwestern, Purdue, Iowa, and even Minnesota.
Sure, we can all list flaws from Wisconsin, Northwestern, Purdue, Iowa, and Minnesota -- but we have our own flaws.
Minnesota won 3 of their last 4 games after firing their defensive coordinator. In those last four games, the opponents only scored 14.8 points per game -- Wisconsin, Purdue, Georgia Tech -- teams that generally scored significantly more than 14.8 ppg. And the Gophers won all three of those games with ease.
It's far too early to say if this past season in Madison was a trend or anomaly for Wisconsin. Even with 8 wins in 2018, Paul Chryst tied Fielding Yost for the second most wins in the first four years in the Big Ten (Urban Meyer is #1). And all of Wisconsin's offensive skill position starters will be returning in 2019.
I personally feel Northwestern should be the favorite going into next season. They went 8-1 in the Big Ten. Pat Fitzgerald proves year-after-year to be the most overachieving coach in the Big Ten (I'd argue he's the single best coach in the Big Ten, now that Urban is gone). Their shiny new transfer quarterback was the #1 nationally-rated pro style QB coming out of high school. And they finally found a running game after their starter retired midseason and their freshman RB significant improved late-season.
I'm not sure what to make of Purdue -- other than they are capable of beating anyone -- and of losing to anyone. Big wins over Ohio State, Boston College, and Iowa. Ugly losses to Eastern Michigan, blown out by Minnesota, and whatever in the hell happened against Auburn. Purdue loses Blough at QB, which is big. They also lose their #1 RB to graduation. They do have Moore returning at WR, however, and he's a future NFLer. And I do like Purdue's coach -- but I won't be surprised if they take a bit of a step back in 2019.
Iowa will always be Iowa. They'll never be bad. Most times, they win 7-9 games. Occasionally they'll surprise and win 10. They are never bad, yet they never really "scare" anyone. The Hawkeyes do return Nate Stanley at QB. And their top two RBs. But they'll be hurting with receiving weapons, as their top three in receptions (two TEs and one WR) are all gone.
Yes, there is no doubt Nebraska improved significantly late-season. But I can counter that some with their schedule. I don't know that NU had a quality win. Yes, they pounded Minnesota -- two weeks prior to their defensive coordinator being fired. Still, nice win, but. Bethune-Cookman, okay. Illinois, umm, okay. And the 9-6 win over a Michigan State team that absolutely sucked when their starting QB went down. Rocky Lombardi was pathetic. Since being named starter late-season, he completed 35%, 37%, and 44% of his passes against Ohio State, Nebraska, and lowly Rutgers (a horrible Rutgers team that only lost 14-10 to Michigan State). Yes, everything about the last month or so of the season was a huge improvement over the start, but there should be some perspective. Nebraska probably wasn't as good as the record indicated late-season, and probably not as bad as it appeared early-season.
Can Nebraska win 8-10 games and possibly the West in 2019? Sure. I don't know that Nebraska is suddenly returning to dominance. That would be a stretch. But I do feel the Big Ten West is wide open -- but I say that also because I don't see a clear indicator that Nebraska is the best of the batch. We do have a much easier schedule, which plays to our advantage. No doubt about it. But if we remove our fandom from the analysis, it's clear that Nebraska still has a ton to prove.
If I was ranking the Big Ten West, 2019 preseason, I'd consider this (although I'd want to do more analysis on returning players and schedules):
1. Northwestern
2. Wisconsin
3. Nebraska
4. Minnesota
5. Iowa
6. Purdue
7. Illinois
