Michigan suffered a shocking loss on the last play of the game at home to Iowa in a dramatic finish that Dave Portnoy called the ‘worst loss’ he has ‘ever seen.’The Wolverines outgained the Hawkeyes 429-285 yards at the Big House in Ann Arbor and looked to be in control despite failing to pull away in the fourth quarter.But Hank Brown threw a game-ending, 16-yard touchdown pass to Reece Vander Zee to lift the No.17 ranked visitors to a 20-19 win over No. 18 Michigan.It capped off a 91-yard final drive kept alive by a costly unnecessary roughness penalty on the home team on third down at midfield. Passionate Michigan fan and Barstool Sports founder Dave Portnoy could not believe what he was seeing as he immediately reacted with a video on social media from a restaurant. ‘That was the most ridiculous s***,’ Portnoy complained. ‘I’ve been watching this on my phone. Iowa stunned Michigan to silence the Big House in Ann Arbor with a 20-19 win Reece Vander Zee caught a touchdown on the final play of the game as time expired’You can’t dominate a game more than that and lose,’ he continued. ‘I actually came away more impressed with Michigan.’That was the worst Michigan loss I’ve ever f***ing seen.’ ‘It’s on them. It was so obvious for anyone watching football they were going to f***ing blow that game.’Despite the loss, he insisted he remains confident Michigan will make it to the postseason as he looked to focus on the positives. He continued: ‘We’re still going to playoffs because they’re really f***ing good. You lose those games. ‘When you dominate, dominate, dominate and don’t put away, then you do stupid penalties and stupid mistakes, you lose. I’ve never been more confident in Michigan though, never.’ It was the first time Iowa has beaten a ranked Big Ten team on the road since 2015, while Michigan’s 47-game streak of winning when leading at halftime, the longest active streak in FBS, came to an end.The dramatic finish was the second involving Michigan in Ann Arbor already this season. They survived an enormous upset on a last-second Hail Mary to beat Western Michigan in Week 1.However, that victory came in extremely controversial circumstances after Big Ten officials wrongly followed protocol and put an extra second on the clock after using a clock not synced up with those on TV to give the Wolverines time for one final play. Michigan lost its first game of the season in a reversal of their dramatic late win in Week 1 Iowa faces Ohio State next week in a massive game after advancing to a 4-0 start to the yearMichigan responded to that poor performance with an impressive win over Oklahoma in Week 2 then beat UTEP, but they have now dropped their first game of the season.Kyle Whittingham’s team face their first road game of the year in Minnesota next week, while Iowa hosts No.7 Ohio State in a huge game. ‘It was a tough locker room,’ Whittingham said after the game. ‘But told them, hey, it’s a shame we let it get away from us. ‘Sometimes in life you get knocked down and things seem tough and how are you going to overcome that, but that’s life. You have to pick yourself up, get back to work.’
