Yeah, for sure.
He was hired in November 2019 so he could have fired Helton right after that (COVID hit in Feb 2020 circa).
Pretty similar timing compared to Miami situation.
Helton
2018: 5-7
2019: 8-5
Diaz
2019: 6-7
2020: 8-3
Agree 100%, there are precedents though: Mike Bohn, who seem to be the better AD in the country now (rightfully so), kept Clay Helton 1 year and half before firing him.
