As a badger fan perusing the board this week, I assumed the OP was asking why the Badgers have losses. Alas, if only wishing made it so we could avoid those things. To answer the question, I thought I would cover all the Badger losses in the Paul Chryst era in reverse chronological order:
2018: BYU 21-24. Ugh. Missed a late FG to tie, but shouldn't have been in that position in the first place
2017: OSU 21-27 (B1G CG). Had the ball in buckeye territory with a chance to win as time was waning, got called for holding on a pass where PI probably should have been called - would have been offsetting and not forced UW to convert a longer down and distance (which, anyone could tell you, is not UW's forte).
2016: PSU 31-38 (B1G CG). Raced out to a huge lead and let McSorely come back and beat us in the end
2016: OSU 20-23 (OT). We had'em, gosh darnit.
2016: @ Michy 7-14. Defensive struggle where Michy had one long pass play to make the difference
2015: NW 7-13. Still mad. Badgers scored to take the lead late, but overturned as refs ruled ball hit ground after three steps out of bounds and WR falling to the ground - he had control, gosh darnit.
2015: Iowa 6-10. Badgers fumbled on the one yard line going in for a score. Hawkeyes run the table, but lose in the B1G CG and Rose Bowl.
2015: Alabama 17-35 (@ Jerryworld, and Chryst's first game). Uh, yeah. Alabama good. UW was in it for awhile, but big plays doomed Bucky that night.
That's it. I hadn't realized that Chryst's teams have only lost one true road game so far. So, you guys getting us in Madison is a break! Also hadn't realized they were all one possession games (except 'Bama).
So, when it comes to this week's game, I am worried about your offense against our defense - we have not been up to our standards, especially on the perimeter. And I am worried our offense has been its own worst enemy with both the play calling and untimely penalties - we are not a high-scoring offense and I fear we might need to be this week. Anyway, keep your collective chin up, I think better days are ahead for you (yeah, low bar at the moment, but you get what I mean).
