Dewey "thinks" there's enough enthusiasm that the money will be there, and he said donors weren't willing to support Coach Davis with the same amount of money. He's basically saying donors are more willing to help [unknown coach] be successful than they are willing to help Coach Davis be successful. That sounds like donors didn't like Coach Davis as much as people say they like Coach Davis.
And before you say, "they don't want to throw good money after bad", if they are truly supporting the program, they should want to help more when the help is most needed.
He also referenced how the donors supported the Belichick hire. With the same people in charge, which is also very concerning, that's not exactly encouraging.
I hope it's a grand slam hire and Carolina never loses another game in my lifetime, I'm just doubtful it's a home run. I'm expecting an RBI double. Anything more than that will be encouraging.
