Physically I like him MUCH better than Super Saver. I just never really like SS all that much, feel his Derby win was a fluke. Never ran a step after the Derby, said he had bone bruising in his cannons and while I believe it a tiny part of me thinks they were just making excuses for a horse that really wasn't that good.
SS never beat much, though really the whole 3yo crop was mediocre minus pretty much only Lucky.
Brethren hasn't beaten anything yet either but IMO looks much more talented than his brother.
