I have two comments...
1 - Shapiro worked for the Globe. Take everything he says with a grain of salt.
2 - Shapiro wasn't the only one to claim inaccuracies in PMPT. Fleet White was another.
I think at the end of the day, you have to be careful believing what you read...especially when it comes to JBR. There are so many sources, and it's hard to really tell what is true.
