"There are a lot of things when I self-reflect that I wish I was better for him in some instances," McVay said, according to Andrew Siciliano of NFL Network.
Reports regarding friction between McVay and Goff surfaced following L.A.'s postseason loss to the Green Bay Packers. McVay was noncommital on Goff's future with the team at the time, saying he was the quarterback "right now."
The Rams then traded Goff and multiple draft picks to the Detroit Lions in exchange for star Matthew Stafford last month. However, the deal won't become official until the start of the new league year March 17.
But despite the reported friction, McVay believes it's "unfair" to solely blame Goff for the team's struggles.
"I'm not going to run away from some of the things that I could have (done) better for him as a leader and a coach," McVay added.
Goff spent five seasons in Los Angeles after being selected first overall in the 2016 draft. He recorded 18,171 yards, 107 touchdowns, 55 interceptions, and a 63% completion rate during his Rams tenure. Additionally, Goff led L.A. to three postseason appearances, including a Super Bowl LIII berth.
But Goff also threw 29 interceptions and committed 17 fumbles over his final two seasons with the Rams.
However, despite a bitter ending, Goff focused on the brighter moments of his time with McVay.
"Regardless of how it ended, me and Sean had a great relationship and did so many great things together," Goff told Sam Farmer of the Los Angeles Times earlier this month.
