I will offer one thought at this stage.
Sovereignty is a talented 3yo colt, BUT....he swerved the Preakness, his Belmont win was over the same trip as the Kentucky Derby, he swerved the Haskell and he's yet to face an older horse.
Journalism, twice beaten by him, has faced older opposition and got hammered by Fierceness in the Pacific Classic.
Maybe a long, tough, season was catching up with Journalism, but it has to be a concern.
Fierceness is a cracking horse on his day and Sierra Leone, when granted a strong pace at 1m2f, is arguably an even better one.
Last year's Breeders' Cup Classic one-two are 11/2 and 7/1 with Sovereignty the 2/1 favourite.
I think in excess of 5/2 dutched one of the pair to floor Sovereignty is better value, as it stands, than 2/1 the 3yo.
