BB1 Craig and BB2 Brian have both gone on to form new successful careers off the back off their wins.
Craig is superb at his DIY stuff and Brian is a natural entertainer.
Can you see anyone in the BB3 going on to such things, I can't.
None of them have any outstanding qualities to go on to a semi-showbiz field. Though some suggestions
Jade - screeching siren to scare birds off the runway at Heathrow
Spencer - advertising Silent Night mattresses
Sophie - as a human anaesthetic in hospitals (thereby saving the NHS millions)
