Northwestern made its sixth comeback from a deficit of 17 points or more since 2004, climbing back to beat Iowa 21-20. The Wildcats have already outdone their 1-8 Big Ten performance last season. And it's not just their offensive upgrades, highlighted by quarterback Peyton Ramsey and coordinator Mike Bajakian, that deserve credit either. The NU defense already has forced seven turnovers, half of its 2019 total. The Wildcats had seven interceptions in 12 games last season and already have six in two games this year. Iowa threw three picks in the second half Saturday. Redshirt freshman safety Brandon Joseph snagged two of them. "This is a mindset," Joseph said. "Not just me but the whole (defensive backs) group. I did it today, but they did it last week, and now we're going to try to go out and do it again next week and the week after that. It's a mindset that we have to get turnovers, and we're going to continue to do that every day." - Chicago Tribune
