I feel like there is some depth there for 2018 if Umu makes it back.
DT: Malumba, Antwine/Umu (Hopefully)
NT: Edwards, Tuiloma
DT: Tuiloma, Franke, Lang
If Edwards can get his **** together, get in better shape and use his size/strength combo it would go a long way to cover up some of the deficiencies in the linebacker group and allow guys like Taylor and Lewis to really show their athleticism. If Edwards doesn't develop this offseason though it seems like a 4 man front could be the way to go with Malumba, Tuiloma, Franke and Sparaco though.
It will be interesting to see if when Coach Drake gets here, how he truly feels about our ability to stand up as a 3 man front as base defense. I thought that I just read something about the fact that we are going to bounce back and forth between 3 man fronts and 4 man fronts based on the situation, and based on an honest analysis by the staff (Eliott) that spoke about the real type of players we have on the roster and can attract to the program. I feel that there are some really creative fronts that we can throw at people with different sub packages. The ONE thing that I want to see from front to back this year is to get back to TACKLING like we did in 2016. The 2016 team was one of the best tackling teams that I have ever seen and it is why many drives were killed. Every guy was willing to tackle like a man. I think Evan Worthington is a stud, he should have a great year, and I think he is a good leader and should step forward and be the leader in the back this year!
