I would assume he would be in the rotation at DT (assuming he signs with Utah), but he won't start over 2 returning seniors.
The defensive line will be extremely good. The LB's are all returning and if Tauteoli and Luafatasanga are healthy, they should be better than 2016. The DB's are the major worry, with only Chase Hansen returning. There is some very good JC talent coming in, but it will definitely be the weak spot on the defense.
