What Rosier did with his legs last night was the difference in the game.
In 2016 VT sacked us 8 times. Kayaa had 9 carries for -55 yards (sacks). 43 QBR.
In 2017 VT sacked us 2 times. Rosier had 13 carries for 85 yards and 1 TD. 77 QBR.
He also had a 7-0 team (Kaaya's was 4-2), a Saturday night home game (Kaaya had a Thursday night road game) and just a better supporting cast all around.
His running is important but so is pretty much everything else.
I disagree on the supporting cast comment if your assertion is that Rosier has the better between the two.
Vs. squad that played VT last year:
Starting, and rotating, a true TrF @ RG
No NFL fullback, which has by CMR's own admission limited our running game and overall balance.
Went from Njoku/Herndon to Herndon/Irvin/Patchan
RB depth is down Walton, Yearby, Edwards and had to move Dallas from WR
Replacing Stacey Coley and Malcom Lewis with some solid prospects in Thomas and Harley will be an upgrade eventually, but a hobbled Richards hurts a lot here
The teams is playing better overall-- both sides-- and being in year 2 under Richt cannot be understated.
In terms of one game, being the "better" QB doesn't mean you're the one that wins. I am not a Kaaya hater, I think he doesn't deserve the beatings he takes on here. I think BK could run through his progressions a lot better than Malik, but schematically, Richt has done some nice things to cover that up using Malik's running ability.
In instances where read one and 2 aren't there, the progression stops and it becomes a running play. Against VT, Richt weaponized this very nicely beyond just working with a limitation. We saw a lot of typical Bud Foster and we read the DE/DT differently than in the past and gouged them for several big gains. You can acknowledge that as an edge to Malik without automatically being a "fanboy"
