The thing is -- they can change the name all they want, but it's going to take a good few generations for whatever the new name is to be used. Think of the now-Xfinity Center. Some people still call it Great Woods because that's what it was forever -- after that it was the Tweeter Center, which was what my generation grew up with it as.
At the end of the day, people will still probably be calling it Yawkey Way for at least another 50-60 years. But classy move from the Sox since Tom Yawkey was apparently a massive racist and refused anyone except Caucasians to play for the Sox while he owned the team.
