Personally I think a lot of his stamina doubts popped up because of his lazy style as a 2year old with that flat spot he always hit. He doesn't seem to have that anymore. For me the only horse that can beat him is BOM who I think is a really good horse who's done all asked of him. This disregards Telescope who I'm on but couldn't trust to win a group one with no prep race.
He has been gelded or else he would have probably won the Derby in a canter, I suspect they will go for a maiden first but my god, that horse has a group 2 engine if they could sort his head out he would make an absolute mockery of 78. If he learned how to race and they ran him in a 1m or 1m2 handicap off 78 he would literally win half the track.
In that case I might be tempted to have a little dabble on the Dante winner finishing last but x.
