I believe Chaos is being sarcastic. And he would ordinarily have a point, except that Greg Cosell has been watching NFL film full time since it was actual film on reels, and Romo was literally in diapers.
I don't think what they say contradicts, actually. Looking at the whole play, it does appear that the first read was to Knox and that on 1st down, the play design would be to take the checkdown if Knox wasn't open and only an aggressive QB with a big arm would try to hit the clearing route (Romo passed for 34,000 yds, putting him in that aggressive bin himself). And Romo is correct - Brown did pause on his route, which is consistent with knowing he's not the receiver the play is designed for and not wanting to wear himself out. Any former QB is going to be inclined to place blame more towards the receiver than to the QB, but the ball wasn't placed where only a receiver running full-out would get it.
