You should read his book it's not bad at all.
In his book he said something to the extent that he was pissed that Bo didn't tell him he was retiring but he told Ricky and that was a slap in the face for Bettis. Said that showed him that UM wanted Ricky more than him.
Again I recommend everyone to take a look at his book. It's very interesting to see how his life was from being little to growing up through football and in the NFL.
