The Partick Thistle midfielder spent several years on the books at Easter Road but failed to make a first-team appearance after coming through the youth ranks.
It is at Firhill where he has shone on the big stage as he helped Archibald's side to the First Division title last term and assumed the armband for their first top flight campaign in nine years.
And Archie is delighted to see his captain fulfilling his potential after a frustrating few years in the capital.
He said: "Captaincy can be a burden to some players but I thought it would help Welshy.
"He is at the stage of the career where I think it has helped him, it has pushed him on.
"I think he did (get a raw deal at Hibs). It didn't help that they went through umpteen managers as well and he was moved about in different positions.
"His position is central midfield and he has showed that. His early form this campaign has been very good. He got a niggling injury but I thought last Saturday he was back to his best.
"I stress to the players before that they have nothing to prove to us. We know what they can do and that is why they are here.
"As long as it doesn't affect their performance, I don't mind them going out with something to prove.
"Hopefully he gets a goal because that is all that has been missing for him."
Thistle head into Monday's Firhill clash knowing that victory would take them above Pat Fenlon's side in the Premiership standings.
It has been a mixed start to the campaign for the Easter Road boss, who saw his side thumped by Malmo and lose their derby clash with Hearts before finding their form to rise to fifth in the table.
Archibald said: "I have seen a massive turnarond in them.
"I saw Hibs earlier on in the season and then a couple of weeks ago and they were like two different teams to be honest.
"Their confidence was high and they looked like a different side. It looked like it was just confidence that was missing from them.
"They have brought in a lot of new players and maybe it is them just gelling. They have shown a lot of character.
"Pat Fenlon had the media circling around him about his job and he was under pressure, but the boys came out and turned it around. It showed great character to do that.
"He is always under pressure. He is at a massive club and that brings expectation with it."
