Possibly, but lots of folks have had torn ACLs and came back; many on the 2017 team. He was the strong side OLB...for sure more of a run stuffer - but he had less sacks in 17 than he had as a sophomore and he was on alot of folks watch lists to break out.
My worry is that what he really suffered from was a methodical, but predictable defense where he was seen only as the contain man. This goes back to the 'why did Mark Stoops take over defensive play calling at Kentucky' worry.
He was noticeably slower in 2017 and it was not due to slow reads.
I get the concern over Eliot, but you are a little all over the place. How is a DL a worry to you? You spent countless posts defending the state of the DL over the last year.
