mean much IMO.
Yards per drive or yards per play are important. What's also important is defensive PER. These are the PERs for the last 10 years:
2016: 132.2
2015: 112.0
2014: 121.5
2013: 113.2
2012: 112.5
2011: 112.6
2010: 116.9
2009: 118.6
2008: 128.0
2007: 110.3
There is simply no way around the fact that BYU's pass D was bad this year and took a significant downturn from years past. It has to get better. I think it will.
