The excellent ex - Racing Post chief editor James Willoughby with a couple of Frankel related articles - also has some good other stuff on that site including global rankings of Trainers , Jockeys . Sires & Owners. James is a bit of a maths buff and also does some bloodstock / breeze up consultancy as well.
Think he is writing a Handicapping / Betting book just now. And has re-started his Countdown To The Run For The Roses again this year. Takes a big interest in US racing as well as the Global scene.
TRC is a good site.
