D line is considered the weakness. Last year we ran the 3-3-5. No longer. Expect a D similar to Boise State's. Though adjusted due to lack of personnel. RichRod fired the whole D staff last year due to lack of recruiting and lack of performance on the field. You will see small, young freshman playing. The new D will be attacking in style and show a lot of movement before the snap. Zona wen through 4-5 LB's last year due to crazy injuries. Some will be back but Scooby Wright III is now in the NFL. Conventional wisdom from Arizona fans is that UA will have to "outscore to win".
BTW, Utah typically doesn't have the speed to keep up with us. Watch out for true freshman 5'6 JJ Taylor on offense.
