Jones went on to describe Watkins as "character and entertainer, a man of no particular size but who was successful in the jealous cauldron of rugby league, who beat the All Blacks playing for his only union club, Newport, played gloriously for Wales, captained the Lions in test matches. He had a prime kicking game, was a master tactician, durable among the beasts of forward play. He was a dazzling runner."
At the other end of the spectrum, he spoke of Carter reaching two peaks during his career – once during the 2005 British and Irish Lions tour of New Zealand, and again 10 years later at the World Cup in England.
"He enjoyed a splendid run after injury in the 2011 World Cup and was probably at the second career peak in 2015 when the All Blacks won again," Jones wrote.
"His first peak was when he took majestic charge of a thumping 3-0 series victory over the 2005 Lions."
Meanwhile, Barnes, the former England and Lions playmaker, had no qualms in distinguishing Carter as "the greatest No. 10 of them all".
"Granted, the 2005 British & Irish Lions were toothless but still, Carter's second test performance against them in Wellington was as close to perfection as any 80 minutes I have seen from anyone, let alone a fly-half," he wrote.
"A decade later, he was to dominate the semifinal and final of the World Cup. The greatest No. 10 of them all."
