If I can butt in for a sec... there was a Nov. 2020 article in Sports Illustrated in which McVay does express some regret in losing Zuerlein; however, he doesn't say a word about Fassel. Is it possible that this is what zn is recalling and not McVay regretting Fassel's loss?

Also, per the excerpt from a January 2020 article below, yeah.. Fassel walked but it was because Mike McCarthy pursued him.
John Fassel - Special teams
At one point during the season, things were so abysmal with the Cowboys special teams unit that the team was heavily considering parting ways with coordinator Keith O'Quinn, a source confirmed to me in 2019, but they instead opted to simply ride out the wave and hope he could turn things around. He didn't, so while a separate source tells CBS Sports of O'Quinn's new expected assignment in the scouting department, McCarthy was busy with yet another NFL poach job -- landing a massive upgrade over O'Quinn by convincing John "Bones" Fassel to walk away from the Los Angeles Rams and join the very Cowboys team he suffered a blowout loss to in Week 15.
The Rams announced the move officially on Wednesday, Jan. 8, and with the reverence and respect Garrett himself couldn't get out of the Cowboys in the final moments of his tenure, but that truly shows just how valuable Fassel was in Los Angeles. Widely known for being one of -- if not the -- most aggressive and creative special teams coordinator in the NFL, teams never know if there's a fake coming, or if there isn't, and that unpredictability fuels the opportunity for big plays in one way or another.
The Cowboys haven't had a dominant return game or special teams unit in ages, but that's all about to change in 2020, and the expectation is they'll go from worst to first in one fell swoop thanks to McCarthy's decision to snag Fassel -- as Rams players mourn the loss.
