Other things to take into account:
What kind of offense was Sims in? Did it fit his strengths? What reads were they asking him to make? How good were those around him? Were his receivers in the right place? Etc.
This topic propagates the only glimmer of grace I will accept when discussing Jeff Sins and his history of suck. Geoff Collins did one of the stupidest things a successful head coach could do in 2019 when he decided to replace Paul Johnson at Georgia Tech. I realize he doubled his salary, but taking a job where he had to transition from the Wishbone to the Pro Style Multiple Offense, coordinated by a lifelong D3 to FCS coach in Dave Patentaude, would require a bold and minimum 3-year transition. His 2019 season was an absolute dumpster fire, as their offensive line couldn't pass block. Their QB's couldn't throw, and they were pretty much a comedy of errors. They basically looked like every Chubba Purdy started game for Nebraska.
2020 - True Freshman Sins arrives in year 2 of the transition. This is the Covid year, and the offense has an older offensive line.
2021- a lot of the older dudes either transferred or didn't return - Sins has to play behind a new offensive line- Offense is a mess. Jayhmir Gibbs transfers to Bama
2022 - Collins fires Patentaude and then hires Chip Long to run a wide open Spread attack.
- Kid shows up at 18, doesn't have a normal preseason practice routine.
- As a true Sophomore, he has to play behind a really young offensive line.
- 3rd season they roll out a completely new and different offense
To say the offense didn't really suit Sims isn't necessarily accurate. It didn't really suit anyone at Tech. That offense was destined to fail from the beginning.
Compounding matters for Collins and Georgia Tech, their defense was just atrocious during this time. The man was an incredibly successful Defensive Coordinator for much of his career and he couldn't put together any type of respectful defense at Ga Tech.
