There is talk about Purdue winning the Big Ten and, possibly, going undefeated. As I posted earlier, I am dubious.
Pudue's early schedule
Akron
@ Arizona
@ Minnesota
Notre Dame
Iowa
I would be surprised if Purdue doesn't lose at least two of their first five games. @ Arizona could be a loss. Minnesota is very tough at home. Notre Dame will be difficult. And, Iowa should be favored.
The schedule is relatively easy after that, but early on will be a handful. @ Wisconsin and @ Penn State are other potential pot-holes.
