Anderson followed up his Friday feat of becoming the first England bowler and only sixth in history to take 500 Test wickets by finishing with a return of seven for 42 in 20.1 overs as West Indies were dismissed for 177 in their second innings on the third day of the third Test.
England recorded series wins over South Africa and most recently West Indies despite struggling to find consistent top-order runs.
It has all put the Yorkshireman in optimistic mood for the Ashes winter ahead. "It's been great", he said of his first summer in charge. Root said: "He's one of the most skilful bowlers I've ever played with".
"They were two hard weeks [after defeats] but what's most pleasing is the resilience and the character we've shown to come back from both of those with extremely strong performances", he said.
"I'm very pleased. It's been a great week".
There are quibbles nonetheless about the readiness of Stoneman, Westley and Dawid Malan in a top five which remains uncertain despite the banker presence of Root and Alastair Cook. There's plenty of challenges ahead but I think we're moving along nicely.
"We should not be afraid of going over there (to Australia), performing at our best and (trying to) do something special".
"What we don't see is what he's been through, those years that he had to put out the cones in 2005 for the fab four bowling attack, the sacrifices he's had to make, the injuries he's had, all the pain he's gone through, we've seen the end result".
Root is adamant progress has been made throughout England's ranks.
"I'm happy with how the whole group's shaping up, to be honest", he said.
"Across the summer, a number of guys have stepped up and taken their games forward". Toby Roland-Jones has come in to the team and looked at home at Test level.
McGregor live gate falls well short of record
Kavanagh - who is now in Florida - added: "The Nate Diaz trilogy fight at lightweight is what I'd personally like to see next". As impressive as the gate was, it wasn't enough to break the record set by Mayweather's bout against Manny Pacquiao.
A bright dyed streak in his hair early in his career belied the fact that Anderson was then an nearly painfully shy and even slightly retiring figure.
Bob Willis, a former England fast bowler and current Sky Sports commentator, went a little further with his praise saying that there has never been a better bowler in English conditions.
"Jimmy's performance speaks for itself", said England captain Joe Root.
"He has just shown what he is still capable of and that he is still desperate to kick on and do some more great things". The resistance was again embodied by Shai Hope, whose half-century at least gave them something to bowl at, but England had in Anderson a man who thrives on a battle as well.
Holder said he wanted the team to build on what they had started in their next two tours, in Zimbabwe next month and then New Zealand.
But he has come back this summer looking fitter and stronger than at any point of his career. The control he has with a ball that's doing a minimal amount and one that's hooping around is remarkable.
"I'd love to be a psychologist and sit down with Moeen over the next few weeks and convince him how good he can be".
Jermaine Blackwood (5) couldn't apply himself to the task and flashed at a wide delivery from Anderson to leave the West Indies 100/5.
"I think we've got a lot to be proud of", he added. Credit must go to James Anderson.
Of those questions, the two most pertinent involve whether rookie batsmen Mark Stoneman and Tom Westley will be on the plane to Australia.
