But after his first match in charge, the captain insisted it was the response from one to 11 which was most significant - and unsurprisingly England's management confirmed within two hours of their victory that they will retain an unchanged 12-man squad for the second Test starting at Trent Bridge on Friday.
While the result is the ideal start for Root's tenure as England captain, the alarming shortcomings within South Africa's performances are concerning ahead of the second Test starting at Trent Bridge starting on Friday [14 July].
A half-century from Alastair Cook proved his return to the ranks would be as seamless as expected from a fine team man and he relished the prospect of making hard runs on a pitch that will be very tough to survive on for long in the fourth innings.
Moeen said: "If somebody had told me when I started out that I would end up with these stats, then I would have bitten their hand off".
A spot on the honors board awaits English cricket's unassuming star after his career-best figures of 10-112 that illuminated England's 211-run win in the first test on Sunday.
Bairstow has hit a half-century in all but one of his last five Tests - maintaining his standards even through England's losing run in India last winter, falling only a single short in his one match without a half-century. They made the wicket look easier than it was.
With a 97-run lead in hand, England got off to a fantastic start in their second innings as Cook and Keaton Jennings put together an 80-run partnership before Jennings was caught behind off the bowling of Morne Morkel for 33. "If I'm being honest, I thought if we batted well, we'd make a decision around tea and try and get in a good position going into tomorrow", he said after the match.
South Afirca's bowlers enjoyed a devastating morning, taking seven wickets at a cost of 63 runs - although, at the same time, every success increased the sense that they may have a hard chase on. After the performances of Ali and Dawson, albeit on a very helpful surface, the spin worries have been eased but consistency, rather than talent, has been the issue with Moeen.
The one disappointment for South Africa in the session was when Bairstow lofted Maharaj to long-off, where Philander dropped a seemingly simple catch under grey skies.
Incredibly, nine wickets fell in just 36.1 overs as England struggled to adapt to the conditions and played far more aggressively than was required, though South Africa still needed a testing 331 runs to win.
Only three sides have made more than 200 to win in the fourth innings of a Lords Test. "It's nice to get that [nickname] out of the way", he said with a smile.
Root will be asking them then simply to continue in the same vein in pursuit of a 2-0 lead in this four-match series.
"It's really important after this Test match that you don't nearly fall into the mental hangover of the tour that we've had so far, so that will be one of my most important jobs and the senior players this week".
