Well at last Sheriff makes his debut tomorrow at Yarmouth. In the first division of the maiden Bell saddles Jawan who has been in the same gallops as Sheriff, House Edge and Demurer. He also did an impressive gallop on Saturday. From the jockey bookings you'd have to think that Jawan is expected to run a big race as Bell has put up Atzeni. By the Australian import Sepoy he is out of a once raced maiden mare who is from the family of Efisio. Worth considering I would think.
Sheriff, who is by Lawman out of a One Cool Cat mare from the Loder's Marling/Marwell line (so a better family than Jawan) is ridden by Steward, a Bell mainstay. Given that his heat appears the tougher one I'd think only an EW interest is worth considering at best.
However on what I've seen on gallop videos there is not much between these two colts. Jawan may be the more ready.
