Heading into the final round, England knew they almost certainly needed a big bonus-point win in Cardiff to have a shot at a first title since 2020.
Narrow victories over France and Scotland came through a more conservative gameplan, before Borthwick delivered on his promise that his side would play more aggressively in attack during the seven-try win over Italy.
England were even more ruthless in their final game in Cardiff, as they scored 10 tries to hammer Wales at the Principality Stadium
Picking three ‘fetchers’ in the back row helped lay the platform for England’s dominance, with both Curry brothers and Ben Earl bossing the breakdown.
“I think England have got the best back row in the championship,” former Scotland captain John Barclay told BBC’s Six Nations Rugby Special.
“Both Curry brothers and Earl were world class. It is not just the breakdown, but there is a physical raw edge to everything they are doing.
“It all makes your job so much easier, their back row were unbelievable.”
In this year’s Six Nations, England lead the way for turnovers won (36), slowing down their opponents’ ruck speed, and jackals won (21).
The depth in the back row is only growing after 20-year-old Northampton Saints flanker Henry Pollock scored two tries on his debut, 21-year-old Chandler Cunningham-South also dotted down twice against Wales, while number eight Tom Willis, 26, impressed on his three starts.
