Bringing this into a more Argyle discussion, I'd imagine as has been said that there has been previous offers for Argyle since JB took the helm. Under JB's self imposed due diligence many were found to not have the funds to be the new/next owner and some were deemed to be frivolous in their intentions for the club.
With every day Argyle becomes a stronger proposition both on and off the pitch and I am sure if a suitable worthwhile candidate presents itself that JB would not stand in the way of the club to progress. As we have seen when Simon Hallett and John Morgan became board members last year, it is not JBs train set to pack away if someone else wants to play with it but it has to be the right thing for Argyle. All which makes for James Brent not only being the best option since administration but possibly the best option ever in the chair at Home Park. He has brought about a professionalism that has been wanting since I've been going to Argyle (30 years) and whilst we've had autocrats or governance by proxy we've not had someone who first and foremost put the business before the love of the club, that came later.
We won't see his like at HP again, as being someone that was necessary and should have been more widely acknowledged for what he achieved. We will not see his like come and rescue us a second time so when/if a billionaire comes knocking I'd hope he and his board would make the right choices when/if it should ever come to pass. I'd also trust JB to ensure after he goes he will leave us in a better position than now.
