The part that was good about Goldberg's promo wasn't anything he said, it was that he came out there, legit looking choked up and emotional about what was happening around him instead of selling that its all fake bullshit. It was like the polar opposite of the kind of terrible pandering shit Seth Rollins was spewing 3 hours prior. Even Roman's promo was better than that (even though he came off as a dick) because Rusev played the funny heel and Roman got off like 2 good lines (I thought the 911 line was good) and then that was it.
Incidentally, Roman/Rusev would be a *great* double turn, even if its never happening. I've always though Rusev was one of the guys who could play babyface and do it pretty well if they needed him to. There's lots of guys who I just can't picture switching (e.g. Sami Zayn, or Seth Rollins, who is coincidentally doing a terrible job as face now) but I could see it.
