The 'Rat Pack' comprised of several Magpies players namely Johnson, Dane Swan, Alan Didak and Heath Shaw.
"Me and 'Dids' were coming to the end of our careers anyway. Heath was traded (to Greater Western Sydney), which was a bit of a shock, but that's the game," Johnson said.
"Bucks has always got along really well with us. Me and Dids probably played a hundred games with him as our captain, and we had a good relationship with him.
"Bucks was certainly grumpier on the field than as a coach. He's a pretty tame coach, he keeps his head, and he's very approachable. Bucks' door is always open to every player.
"If there was ever an issue, we'd talk about it like grown men. Exactly the same as I did with Mick (Malthouse). I've had arguments with both – more with Mick – but we'd work it out."
