Tafua: 68 tackles, 16 TFL, 5 sacks, 2 PBU in 2 years
Tupai: 53 tackles, 9.5 TFL, 4 sacks, 2 PBU the past 2 years

And we have a TON of young DL talent, but only Tafua and Tupai have much experience:

F. Pututau- 3* RM with offers from CU, UW, OR ST, Vandy, WSU

R. Freshmen:

Not a ton of experience (which is a theme for all of Utah's 2020 defense), but a bunch of talent. If Kaufusi makes it into heavy rotation at DE I'll be very impressed.
