With due respect, there are very few people in speedway who have achieved what Eric has and is still doing in Speedway. His brother may have been a better rider but that's all he was, a rider. There have also been better riders than Nigel and they still would not warrant writing and selling their life story.
Eric has done it on every stage in speedway and in his own way. You obviously have never been in his company and heard him spin his yarns and exploits, sometimes with Ian Thomas, and keep a group amused for ages. He has a roughness that some don't take to but nevertheless he is one of the great characters in modern speedway. Borrow his book and be entertained.
