Charlie comes across as classy, knowledgeable, and unbiased. That makes his commentary interesting and useful.
Johnny comes across as a shill for Russians, with unnecessary meanness towards the rest. That makes him irrelevant. Just annoying noise.
I agree. I also like Tanith. And John Coughlin. And Tonia Kwaitowski. And Ben Agosto. And just about everyone other than Johnny and Tara. Tanith has been getting a lot of air time lately, I'm starting to wonder if she's going to replace Terry Gannon. Tanith has done some gymnastics color commentary for NBC as well. I'm watching swimming ATM and Terry Gannon is generally excitable and pretty pro-American, but having bias towards Americans when you are American and broadcasting on a US network at least makes more sense than Russian boot licking.
