Penn State isn’t far behind as it is ranked 20th with a plus-10 turnover margin.Notre Dame safety Xavier Watts has accounted for seven of Notre Dame’s takeaways with six interceptions and one fumble recovery.”I think in a lot of ways, they are built similar to us,” Penn State coach James Franklin said. “You look at their turnover ratio numbers, you look at their explosive play defense in terms of defending and limiting explosive plays. … And they do a great job of not beating themselves, which I think is a really important thing in college football. It starts with that, and then you kind of go from there and play to your strengths and things like that.”Penn State is 4-1 all-time in the Orange Bowl and will make its first appearance since 2006.Notre Dame’s last postseason game in Miami was the 2013 BCS National Championship Game, but it hasn’t played in the Orange Bowl since 1996.
