Watch: MLB commissioner serenaded by unhappy fans during draft

While it cannot be fun to hear how much thousands of people dislike you repeatedly on national television, Manfred's reaction while trying to announce the final pick of the first round is an example of why he's so disliked. 

His facial expressions and body language don't indicate that he recognizes or acknowledges any of the grievances fans have with him, and instead, gives off the energy of a father disappointed in the behavior of his young children. 

Compare that with NFL commissioner Roger Goodell, who has been receiving boo essentially since he took the position. With the 2020 draft held virtually due to COVID-19, Goodell leaned into the tradition by having fans boo him virtually from their homes. 

NHL Commissioner Gary Bettman also receives a similar welcome at events, and this year's draft in June encouraged the fans in attendance to turn up the volume. 

Why fans hate Manfred

Rob Manfred's tenure as commissioner of MLB hasn't been easy. 

He's had to deal with COVID, the fallout from the Houston Astros sign stealing scandal, a lockout and franchise relocation since he took the job in 2014. 

For many fans, he's handled all of those circumstances poorly. 

In regards to the Astros, MLB decided to fine the team $5M take away some draft picks and suspend both the GM and manager for a season. No players still active in the league at the time of the decision faced any discipline. Manfred also said he wouldn't vacate the title when asked, referring to the World Series trophy (also known as the Commissioners' Trophy) as just "a piece of metal."

He's since apologized for both that comment and his inaction toward cheating players, but the damage there was already done. 

Manfred has also received criticism for how he handled negotiations for the most recent collective bargaining agreement that resulted in a lockout and delayed the start of the 2022 MLB season, as well as the Oakland Athletics' pending departure from the Bay Area. 

In a high-profile job like Manfred's, every decision made will have its critics, especially in the age of social media. Gaffes, missteps and lies are much easier to observe and remember. With few other opportunities for fans to share their thoughts directly with Manfred, expect to hear those boos rain down every time Manfred addresses a crowd.
