Wellens and Peacock have tangled many times on the pitch, but it is playing alongside the Saints icon that Peacock will recall more fondly.
“I think ‘Wello’ would have liked to have bowed out on his terms, rather than his injury’s terms,” Peacock told Rhinos TV.
“But I know it’s been something that he’s been struggling with for a while, and unfortunately he’s had to pull the pin on things.
“I know I’ve played against him a lot, but I’ll probably remember my memories of playing with him for Great Britain most.
“One of the good aspects for playing for Great Britain is that you get to play alongside players that you probably would never play alongside otherwise.”
Peacock feels that Wellens is one of the best players he has lined up alongside, and the full-back’s qualities go well beyond what he could do on the pitch.
“[He’s got] character. Off the field, he’s a great bloke, who loves the game. He loves St Helens, he loves rugby league.
“He’s a competitor who always wanted to win. He always put his body on the line – I think that’s what great full-backs do.
“He’s also a bloke with great values.
“I think he’ll be a loss for St Helens, they were also a better side with him on the pitch.
“I’d say he’s been the best full-back in Super League over the era.
“The character of the man will stand the test of time. I think he’s one of the best.”
