Michael,
I must have higher standards for impressive. He certainly didn\'t do anything wrong so I can\'t trash him. However, you can\'t have it any easier than that. He was loose, going slow early, and KCB didn\'t fire. Sort it Out was a little more suspect to run well, but he didn\'t either. Most of the other horses that could have challenged late didn\'t have much of shot under this pace scenario. He proved more today than in the past because at least these weren\'t garbage cans behind him, but IMO, he has a lot to prove yet.
I consider impressive to be dueling off a \"major contender\" early, repulsing a bid from one of the stalkers and then drawing off in fast time. He has yet to be tested by a reasonable pace and another horses of quality and we know what happens to lots of horses when they do.
Personally I think the most impressive thing is that Frankel is smart enough to not have had him wound up 100% today with the Derby being the target. So I do think there\'s more in the tank.
