Chris Harris of all people had a pretty decent series too. Don't think he did much in test cricket other than that.Having Astle and McMillan getting handy wickets helped in that era too. When things were a struggle it meant the main bowlers wouldn't be over bowled too much (still got injured though).
England also had a revival of sorts after this series in reaction to th criticism for losing it. The good performances in subcontinent followed under Hussain when no one gave them a chance.
