Richard Williams agrees in The Guardian, stating that Rosberg knows Hamilton has the "edge in outright speed", while next year he could have been on "something close to a hiding to nothing".
"He might not want to spend a year defending his title under further critical scrutiny from those who believe that his success was made possible only by a couple of engine failures on Hamilton's car," Williams continues.
Hamilton, meanwhile, who spoke to Rosberg before he made his decision public, insisted he was not surprised by his former best friend's early exit from the sport.
But while The Telegraph's Oliver Brown claims "Hamilton will want assurances that his alpha-male standing at Mercedes is not under threat" when they pick his next teammate, Rosberg's retirement could in fact help the Brit. Hamilton was facing disciplinary action from Mercedes after disobeying orders at the Duel in the Desert.
"Hamilton will be left off the hook for defying team bosses in Abu Dhabi as they frantically try to find a replacement for Rosberg," writes Ben Hunt in The Sun.
"The German's decision to quit F1 has left Merc chiefs with a real headache for 2017 - and they won't risk aggravating their other star driver."
Eason agrees, adding: "Toto Wolff's threaten to fine, suspend or even sack Hamilton for 'anarchy' in Abu Dhabi when he did his best to sabotage Rosberg's title attempt are now consigned to the bin.
"The Austrian's only concern now is to find a driver of stature who has a chance of standing up to a driver ruthless enough to discard a gentlemen's agreement to pursue his quest for glory."
It is claimed that Rosberg only told Mercedes bosses of his decision on Wednesday, while he was "almost in tears" when speaking to Toto Wolff on the phone.
When the 31-year-old, who studied Zen philosophy to control his emotions throughout the season, made his announcement in Vienna, "it landed like a bomb out of a clear sky", claims The Daily Mail's Jonathan McEvoy.
"Retirement out of the blue was probably the most quixotic thing Rosberg has ever done." he writes. "He was a grafter, not a grandstander.
"He will not be remembered as a truly great driver, but he beat one in Hamilton. Rosberg's mental resilience, as four-time champion Alain Prost noted the other day, when everyone told him he was no equal of Hamilton, is a testimony to his character and work rate."
