The guy was top 5 in yards, yards/game, passes per game, YPA, TDs, QBR, game winning drives and comebacks, passing TD%. He was twice NFC Offensive Player of the Week. He won 4 playoff games, including the SB.
These are facts. You have referenced opinion pieces--like your own ("I don't think he was top 5").
As I said, Tomlin was McVay several years ago. If you now want to change your position to "<1% chance McVay finishes his career as the best HC ever"---yeah, that's where I was already, lol.
