Plus they actually spent the money to get some good players so they could compete with the YANKEES.
Joe Cronin, Jimmy Foxx, Lefty Grove among many. Tom Yawkey bought those players in the 1930s to compete with the Yankees. He spent a lot of money trying to win.
I was mostly referring to the lack of investment in Fenway park in the last thirty years the Yawkey family owned the team.
Fenway was a real Sh#t Hole in the 1980s and 90s. There were never enough bathrooms. The men's rooms had one big stainless steel trough to pee in. People waited in line so long, they would just piss in the sinks. You would miss a complete inning if you need to go. That was for the men. The ladies would miss at least a full inning, if not two going to the bathroom.
The seats were still the original oak slats installed in 1912. Your backside hurt to sit on them for 3 hours.
They never had nets up for foul balls. Multiple people were hit by foul balls especially in short left field that sticks right out to the third base line.
Of course, they added the Green Monster seats. Which are a very expensive novelty. The most expensive outfield seats in MLB. Plus, unless you are in the front row, you can not see half of left field.
There are still obscured view seats, which you can not do anything about the 12” wide I beam holding up the grandstand roof.
However, they added a lot of seats on the roof. They also added two pavilions. One out the right field line. The other out the left field line. Right field is a large bar. Again with its own bathrooms. The left side is family oriented. No Alcohol is served. It is rented out by many family/youth groups. Basically, the new owner group spent hundreds of millions of dollars improving the Fenway experience. It might have been cheaper to tear it down and rebuild from scratch. However, the city/people of Boston would not allow that.
