There are all sorts of reasons players become 'Bosmans'. Some not good enough for the level of their present team, others because they don't fit into a managers plans or maybe fallen out with a manager or there is a glut of players in their particular position, at that club. Some too expensive (like Euell and Sol Campbell, down the road), others want to move on because they're stale, or want to further their career elsewhere, or have only been offered short-term contracts. All of which, adds up to the fact that there are decent players out there, not currently under contract, who could do a decent job for Saints in League 1 to Championship level. I certainly think Dan Harding comes into that bracket.
