I haven't seen anything about that yet.
I've seen a few people ask whey Krauss isn't going to be on the sidelines this year and a few have speculated his job in Indy is taking too much of his time.
Since Barry was on the sidelines last year during the PPV, and he was also the reporter during the radio broadcasts, I can only assume Chris takes that role as well.
Is this step one for his move to replace Eli in a few years? Seems logical.
