And that's not to mention an opponent who played an excellent first 40 minutes of rugby to seemingly take the game by the scruff of the neck.
Lesser teams may have crumbled, but England stuck at it and all the momentum was behind them in the final half as Wales finally faltered.
After three previous defeats in the final, all at the hands of New Zealand, it was a sweet victory for England for whom Ross Moriarty and Elliott Stooke both played key parts throughout the tournament.

It was Wales, however, who made the early running as Sam Davies' well judged cross kick found winger Ashley Evans for the game's opening try.
Davies and Henry Slade then swapped penalties before Evans swooped to intercept an all advised pass to score under the posts.
England needed a boost and thought they had it on the stroke of half time. Lock Tom Price dived over but the try was disallowed for fellow second rower Dom Barrow using his knee at a previous ruck. Barrow was sinbinned to rub salt into the wound.
Wales looked to take advantage of the extra man at the start of the second half but England held out - just - before launching their comeback.
However, the rub of the green still seemed to be going against England when Danny Hobbs-Awoyemi had a try disallowed for crawling along the floor. It seemed a harsh call.
England upped the pressure and Wales suddenly looked rattled. A sweeping move saw Jack Nowell scythe his way over and England were back in it.
Five minutes later, Sam Hill powered over for the second and Slade's conversion gave England the lead for the first time.
Desperate for ball, and seemingly tiring, Wales resorted to illegal tactics at the breakdown as time ticked away and Slade was able to pad the lead with two penalties.
The game had turned on its head. England were in control, Wales having to chance their arm, and the men in white held on with some ease to take the crown.
