That's debatable.
The infrastructure is definitely much better but that isn't Dino's doing.
His first 3 years including his high water mark 2018 relied on inherited talent at a lot of positions (the least of which being Dungey). He turned over a roster to Fran that lacked any first line QB, let alone a functional backup, and that needed complete rebuilds to both the OL and DL. Not to mention the 2 deep beyond Pena and LeQuint at WR and RB were pretty weak overall. TE / LB / DB are the depth charts that were good to strong without a ton of work on Fran's part, even though he still added some really nice pieces to each of them.
Dino turned over a 2-6 ACC team, Shafer turned over a 2-6 ACC team. So I don't feel Dino turned over anything that much different than what he inherited, and due to the QB depth, arguably worse.
I would say the infrastructure, the coach is definitely a part of that. It isn't like new facilities just got built once Fran was hired. Part of the growth of the program under Dino's 8 years, but not sure how you can separate that from the head of the program.
To use the last 2 years before a coach came in, much different inheriting a team that went to back to back bowl games vs. a team that went 3-9 and 4-8. It still took Dino 2 years after Shafer was gone to get more than 4 wins, so there was some level of coaching/injury luck/recruiting/player development to work with Dungey magic to get the 10 wins.
Team plateaued under Shafer just like it plateaued under Dino. The base Fran has to work with and the impact talent he brought in to complement from the portal, would argue expectations are higher than a bowl game and exceed the pre-season expectations of any year in recent Syracuse memory except entering 2019.
Either way, transfer portal does it make it difficult to assess, so much more power to re-shape a roster quickly nowadays.
