The 52-year-old is intimately familiar with the market, both as coach and nowadays mentor for various players.
"As much as competition for franchise contracts is reasonably high, it's also surprisingly easy to fall into a comfort zone. I don't think one should be overly concerned about the number of players that move yearly. If you go for the right reasons and you use the system well, it's a good thing."
Nosworthy cites the example of former Proteas all-rounder Justin Kemp, who arguably took too long to make his decisive move from Eastern Province to Northerns in 2003.
"I might be a bit biased because I was involved in that, but Justin was an interesting example. He did make his international debut while still in Port Elizabeth, but his career only really ignited once he moved to Centurion," he said.
"He was fiercely loyal to the region as a Queens College and EP stalwart and there's nothing wrong with that. Yet if he made the move earlier, could he have perhaps played even more international cricket? I know my answer."
Tony de Zorzi's move from the Titans to the Cobras is an appropriate current example.
The 24-year-old left-hander has become one of South Africa's more accomplished young batsmen in a competitive and successful environment at SuperSport Park.
There would've been more than enough reason to stick around.
Yet he's swopped that familiarity for the demands of competing at what is now the hotbed for SA's promising batsmen - Janneman Malan, Jono Bird, Zubayr Hamza and Kyle Verreynne.
"A fresh environment is in many cases a good thing. And given that it's not necessarily that difficult to move if you've developed a pedigree for yourself, players should do it if it's for the right reasons," said Nosworthy.
But there can't be denying that some players over the years have jumped from ship to ship without improving meaningfully in the process.
"Yeah, some departures are all about an agent making a quick buck. There are a lot of very good agents in South African cricket, but a few who really just want to pocket. That's no good for the players or the system in general."
