I can't personally speak to a direct comparison between CH and VS as DL coaches (because I never had the opportunity to watch them in action), but new coaches usually get glowing compliments from some of their players. Vic hasn't been loved universally (see portal action) and neither was CK, but they both had their supporters while in the saddle. I remember even "Sweaty" getting props from "some".
In any case, Chad's wasn't a poor coach by a long shot and he was/is a solid recruiter, especially in the Poly community. This from the UNLV site (where he is now DL coach;
"Kauha'aha'a spent the 2019 season as USC’s defensive line coach as the Trojans ranked 28th in the nation with 35 quarterback sacks and featured First Team All-Pac-12 lineman Jay Tufele and second-teamer Drake Jackson, who was also named a First Team Freshman All-American by 247Sports. Kauha’aha’a previously assisted the line at six other schools: Boise State (2018), Oregon State (2015-17), Wisconsin (2013-14), Utah (2011-12), Utah State (2009-10) and Weber State (2005-08). No less than 10 of his players have made it to the NFL, including 2013 first-rounder Star Lotulelei from Utah."
And, less we forget, his immediate supervisor and influencer was Clancy "Don't Need No Money" Pendergast; arguably the worst DC at USC in the past 30 years. Pretty hard to shine as an assistant when your Coordinator/Boss is a stone plug.
CK never had a fair shot at USC, IMO ... and that is not a condemnation of So'oto ... but CK's timing and specific circumstance worked against him. FWIW, personally I really like Vic a lot.
