Main difference: Ark played a ton of 3-high, Iowa-state style D against us. They played much more mixed against Ole Miss: some of the 3-high, but also some man free (1 safety high, man everywhere else) and a lot more 2-high. The 3-high is Sark’s kryptonite and his main way to beat it is running out of 12 personnel (or in 2022 against ISU, even 3 TEs). Ole Miss punished the 2-high and man coverage.
The other thing relevant to Quinn is that Dart will take chances—early in the game against Ark, he threw into tight windows or against some decent man coverage on go routes and just made good throws. Sark’s offense is designed to produce wide open shots. Watch for contested throws/catches some time—we get the occasional like Golden’s TD catch on the sprint out, but Quinn does not test windows very often, and Sark has appeared to coach him not to. Dart may throw some more INTs than Quinn, but he also gets the payoff when he fits into some tight windows.
Also, Ark had at least one major coverage bust against Ole Miss but none against us (or none we made them pay for).
