Just did a bit of research based off nothing but returning starters. GT returns 8 starters on both sides of the ball (5 on O, 3 on D) which is historically low.
Since 2010, only 19 Power 5 teams and 47 total teams have had 9 or fewer returning starters for the next season, with an average year over year win differential of -1.7 (e.g. teams with that few of starters on average win ~2 fewer games that season then the one before)
For Power 5 teams with 9 or fewer returning starters:
4/19 had the same or more wins the next season, and 15 had worse seasons.
The exceptions were a 2017 Michigan state team that went from 3 wins to 10 wins
A 2015 Clemson team that retruned a healthy Deshaun Watson
and a 2014 Arizona State and Boston College teams that met their previous season win totals.
Expanding it to G5+P5 teams
4/29 have met or done better the following season with 8 or fewer returning starters, with those win improvements being 4 (clemson) 1,1,0. Its definitely doable, but it will require a breakout year for quite a few people.
Schedule as I see it
@Clemson -Lol
USF - Win. They lose a lot on an iffy defense, but return basically everyone on offense. Close game last year, should win at home
Citadel- Win. I think people are horrifically undervaluing them, but this should be spooky close. They were tied with Alabama at basically half last year.
@Temple - W/Tossup Vendetta game for them. Still got a lot of questions about us, that should get answered in first 3 games. Clemson wont be a good barometer.
UNC - W. They have been terrible, and should be better this season. Return a ton of players on Offense. It took us until the 4th Q to put the game away last year. They were better than their record last year, and itll show this year.
@Duke - L. Daniel Jones is a pain in the ***, and Duke loses about the same amount of production at us, so they are also a huge wild card. Id take us at home, but not on the road. Well know what Duke looks like after their first few games.
@Miami - L. In 2017, when they won the Coastal, they were 4-0 in games decided by one score or less. They were 1-3 last year. Overrated in 2017, underrated in 2018 IMO. Id prefer our chances at home, but it should be close given what the transfer portal did to them.
Pitt - L/Tossup. Loses their RB, but they always seem to have their RB have their breakout game against us. They do lose basically their entire OL, but with us losing the entirety of the front 7, there isnt much room for exploitation.
@UVA - L, W if at home. I cant state enough how much better our even year schedule is
vs VT - W/tossup. VT returns damn near everyone. Rough season last year, but they will catch up to their usual magic. They did lose some through the portal.
vc NCSU. Toss up With the demise of FSU, the middle of the atlatnic is rough. NCSU and BC lose everyone, Louisville is a trainreck, and they will be worse than their record for that reason.
UGA - L
4 lean wins, 3 tossups, 5 lean Losses.
