Outside of one quarter during the Utah game, BYU's defense was solid all year long. With a lot of key returning starters and (possibly) improved units, there is little reason to believe it won't be just as good (if not better) in 2012.
Here is what the participating members of Cougar Nation thought:
Average Response: 13.8 interceptions
Average Response: Kyle Van Noy (the last "y" in that name is actually from Preston Hadley's last name
Average Response: 1.2 punt/kick returns
As always, this year's BYU team has a lot of expectations attached to it. Barring a string of serious injuries to key defensive players, I think the overall idea that the defense will be better in 2012 than it was in 2011 (and it was very good in 2011) is well warranted. This defense has a lot of returning starters, and BYU fans clearly will be surprised if it takes a step backwards in 2012.
Last year was pretty special with the two touchdown returns, but the chances of something happening that hadn't happened since 1996 are probably low. Nevertheless, Cody Hoffman and JD Falslev are exciting players to watch on special teams. It's not surprising to see so many responses for at least one touchdown return.
