I understand the Bob is lacking. For those who would like to see him retire, would you honestly turn off the volume of your TV and listen to the TVN with his replacement? With a 7 second delay, it's incredibly agitating for me to listen to the call and it not remotely sync up with what I'm watching.
Back when we were young, we listened to JW a lot because only half our games were Televised. I guess my point is, I know it sounds nostalgic to turn the volume down and turn on TVN but it's not practical. With every game televised now, the only time I would listen is if I were not able to watch a game in person or on TV. Given my love for TN, to deviate from either two options would have to be a major life event.
I also don't see them going out and breaking the bank for anyone that most would consider an upgrade.
