Agree. How do first time coaches do? I’d have to check their records. I’m guessing they are as good as rookie qbs winning super bowls.
Most HOF coaches.
-Paul Brown's first team was the Browns
-Vince Lombardi's first pro HC job was the Packers
-Tom Landry got his HC start on the Cowboys
-Chuck Noll on the Steelers
-Joe Gibbs on the Redskins
-Shula didn't have his most famous run on the Colts but he brought them to a Super Bowl.
-Parcells first HC was the Giants run.
-Cowher on the Steelers.
-Jimmy Johnson's first HC was the Cowboys
-Bill Walsh on the 49'ers.
If you want current examples. McVay's first HC job is his current one and he won a Super Bowl.
Of the current playoff teams.
-Ravens: John Harbaughs first HC job
-Bills: McDermott's first HC job
-Texans: Ryans first HC job
-Browns: Stefanski's first HC job
-Dolphins: McDaniel's first HC job
-Steelers: Tomlins first and only HC job
-49'ers: Shanahans first HC job
-Lions: Campbells first HC job (aside from an interim run)
-Eagles: Sirianni's first HC job
-Rams" Mcvay's first job as mentioned above
-Lafluer's first HC job.
Only 3 of the 14 playoff teams don't have a coach in their first HC station. The Chiefs (Andy Reid), the Cowboys (McCarthy), the Bucanners (Bowles). One of them won a Super Bowl with their first team (McCarthy) and the other made his name and went to a Super Bowl with his first team (Reid).
