I think Edsall brought in some good young talent and I don't think this is a major rebuild. I think offensive coaching has really held the team back and UConn did not have an experienced OC this year and it showed.
This year, UConn should have won 4 to 6 games given the schedule: Holy Cross, Wyoming, Vanderbilt, UMass, Yale, Middle Tennessee.
I think Benedict is thinking this way as well and he doesn't want to see the program torn down and rebuilt over 3 to 4 years. It may take a few years to get to a 7 or 8 win season, but it shouldn't take long to get to being consistently competitive. Bring in some key talent from the portal and hire a competent offensive coaching staff and I think the program is stabilized. And, I think bringing in Mora now will help prevent players from leaving as Mora is a well respected coach with an NFL pedigree.
I think you will see some of the coaches stay, but just because they are staying doesn't mean they won't be evaluated next year. Some of the assistants that could stay: Spanos, Dottin-Carter, and maybe Corey Edsall (recruiting) as well as some of the off the field staff that are involved in recruiting.
