It was because of the bungee clause.
Flintoff’s agent, Andrew Chandler, explains why his client has turned down an incremental England contract which might have stopped him playing in the occasional lucrative Twenty20 tournament:
“There were one or two things in it that made it difficult to sign like he wouldn’t be allowed to participate in dangerous sports and he’s possibly doing a television series in which he may do bungee-jumping.”
What more reason could there be?
Chandler goes on to use the phrase ‘has to’ in an unusual way:
“He’s got three young kids and Andrew and his wife Rachel both spend reasonable amounts of cash so he has to make plenty.”
