Considering he went 7-6 last year with that prehistoric offense—and a better defense that had Redwine, Johnson, J-Jackson, Willis and M-Jackson—he'd have done worse, or at best the same.
Up and down as Enos has been, he's absolutely had more of a positive effect on Williams and Perry than Jon Richt ever would've had. Period.
And sure, Richt might've beaten GT and FIU ... but also might've lost to Pittsburgh and Virginia. Goes both ways. Let's not act like dude didn't have two four-game losing streaks over three seasons—and didn't lay an egg to a four-win Pittsburgh team in 2017 when the Canes started off 10-0 that season, miraculously.
He left a 7-6 team that got smashed by Wisconsin in the bowl game, 35-3 and had no answers how to improve on that—as he wasn't going to shake up his offensive "staff"—therefore there's zero reason to believe the man goes bette than 7-6 with a depleted defense and the same old garbage offense he trotted out in 2018.
