First and foremost, I don't understand how Brock Lesnar is to blame for the low ratings when he was exclusively wrestling on SmackDown, not even the WWEs flagship show. If anyone is to be blamed for the low ratings it should be Triple H and Goldberg, who were the ones headlining RAW that year for the most part. Secondly, who is to say CM Punk would have done any better? He was never given the full "poster boy" push and even when he had the WWE title for 400 plus days, he didn't set any ratings records. At the end of the day Brock Lesnar was pushed as a dominant wrestler who rarely lost, whereas CM Punk was pushed as a wrestler best known for his promos not his win/loss record. CM Punk lost clean to The Rock twice and once to Triple H while in his prime. Brock Lesnar on the other hand beat both Triple H and The Rock clean on his first try.
