And I'll add this as a big JF supporter. When you listened to his pbp on NBC and now w Seattle he was/is not the same as with Tripp. He threw out softballs that whoever analyst he was with rarely hit. But with TT, the chemistry, inside jokes, ongoing 'memes', along with various shenanigans made for entertaining broadcasts. It's what kept me watching most all the games over the 10 years of meh hockey.
I liken it somewhat to Lewis and Martin. When they broke up Dean was never near as funny but he was still Dean MF Martin.
John with JT is well... not the same.
