the last eight in 2011 as a care-free 18-year-old was seen as the springboard to a top-10 ranking and grand slam success.
Now 21, Tomic, who was dumped from the second round by Czech Tomas Berdych, is ranked 86th in the world and has not since advanced beyond the fourth round at the majors.
Compared to Kyrgios, now glowing in the light as the "golden boy" from Canberra, Tomic's brand has been tainted by a string of controversies.
He was kicked out of the Davis Cup team for attitude problems and stuck by his hotheaded father-coach John Tomic, who was convicted by a Spanish court of assaulting his son's former hitting partner last year.
"The last couple of years have been tough for Aussie tennis fans as we've watched Bernard Tomic occasionally show his talent, but mostly abuse it, mock it, waste it," wrote one News Ltd critic prior to Kyrgios's Nadal clash.
"Yet still we've cheered for him, hoping against hope that it's surely just a matter of time until his infantile mind catches up with his oversized body.
"Hasn't happened yet and maybe it never will. Either way, it now scarcely matters because Nick Kyrgios is number one in our hearts.
"This likeable young Canberran has a lovely vibe about him. He's aggressive but controlled, a killer on the court and a puppy dog off it."
