The turnover of players seems to have become a perennial problem (excuse). Why are we unable to keep a core of a squad together? I know we can point to specific reasons as to why certain players have gone that may be outside of the control of Dai, Derek or anyone else, whether that be personal circumstances, England selection, lack of opportunity or just cold hard cash and the need to stay within the cap (Wade, Cips, Hask, Simpson, Hughes, Daly...), coupled with high profile, high quality SH players on short term deals (Le Roux, Beale, Smith, Piutau). The fact remains that this is a worrying trend, and I think the number one reason that we have become un-competitive in recent seasons.
There are a lot of other issues at play - ongoing uncertainty regarding the training ground; players who relocated failing to settle; failure to qualify for Champions' Cup; coaching; club finances - that may or may not factor in a player's decision to leave the club. I'm not saying all of the above have necessarily contributed to the higher player turnover, but if you're an employee in an organisation where just 2 or 3 of these things give cause for concern then you are most likely more open to approaches from other prospective employers.
