When I got back into pool four years ago, I started watching a lot of old matches on Youtube. Naturally I had no idea who Diliberto was and I initially wasn't impressed with his commentary. Seemed slow to the take. He engaged in what I thought of as silly banter. And it didn't seem like he had kept up with the modern game.
Turns out I was the one who was slow to the take!
The more I listened to him, the more I recognized his keen and timeless insight into the game. His warm but dry wit grew on me. And his self-deprecation I came to realize was a result of his humbleness about himself and about the game. Pool can humble anyone.
Later I sought out the few matches on Youtube in which he played. I especially enjoyed watching his seniors match from the 1990s against Grady Mathews, another commentator who did not impress me at first.
I still think Mathews talked too much about his ex-wives - !!! - but he and Diliberto were incomparable when calling a game together. Later on I hunted down one of Mathews' old CDs on banking and kicking. I just rewatched it last week. Decades of experience went into it.
Time and life moves on, but they left an indelible mark on billiards.
