Given that he was done before yesterday's 3;00 full coverage started (and they were only showing 2 featured pairs or amen corner before that not sure what you were expecting)
And he started today 7 shots out of the lead today. He had to earn his way into coverage which he now has. It's no different than anybody else
I'm expecting more than wall to wall coverage of one threesome and Koepka. When I posted about Cantlay he had played his last 27 holes in 11 under, by far the best of anybody in the field. But you'd never know it if CBS was your only source of information. C'mon man, this is pretty basic.
