Does Head Coach Kyle Shanahan Need a Super Bowl for Validation?

Since the hire of current head coach Kyle Shanahan back in 2017, the San Francisco 49ers have a total record of 82-66 with five postseason trips. Four of them included a Conference Championship game at worst, with two of those years ending in the Super Bowl (both losses, 2019 & 2023).

Throughout his tenure, he's had to endure multiple quarterbacks, injury riddles rosters and now disgruntled star receivers. Even still, the 49ers have been one of the model franchises in the NFL since his hire. 

However, he has yet win the game's biggest prize as the head man, and that fact might put a bit of a damper on an otherwise all-time great nine-year resume. 

Does Shanahan need a Super Bowl to validate his place as one of the game's greatest coaches?
