That's the same degree of certainty that can be applied to every statement made as to whether we would be better of with or without SL.
If you qualified it by saying we are better off with SL than with the Venkeys,Tan or Risdale then the percentage changes dramatically, and therein lies the nub of the problem as all SL's critics assume that a new owner would be better than the current one.
If SL went everything depends on who replaced him and while we could be lucky in having a another billionaire fan of the club willing and able to lose a fortune on the club, the chances are that as a struggling league 1 outfit, we would have a wealthy, but nowhere near as wealthy, businessman, knowing just as much about running a football club as SL. With less wealth, the new owner would be able to risk less money, so would be more careful about how he spends it, would appoint his/her own people in key positions, who could be just as good/bad or even worse than the present incumbents.
If the new owner had less wealth, then would he/she be prepared to fork out the money for a redeveloped AG ( forget AV as Lansdowns own the land so if they go I suspect a lucrative housing project is top of the list) and would he/she be prepared to fund the academy, bearing in mind the new owner might be more concerned about the return he/she is getting on their investment rather than subsidising a loss making business?
Many fans have demanded a new manager at regular intervals, as we have struggled over the last few seasons, and their wishes have been granted and we have seen each new manager fare worse than his predecessor. Our track record for changing people only for things to get worse is 100% successful since GJ, and I worry that we could achieve the same 100% success rate by changing the owner.
I'm not an SL arse/shoe licker but I think I am a pragmatist.
