As others have stated, he will want them sound and functional. He may give up some of the extreme thickness to get a steer that travels better - a very good thing in my opinion! His roots are still with breeding cattle, so soundness is more of a priority than with some steer judges. I'm sure he'll do a good job and give excellent reasons that are easy to listen to.
By the way, he judged the steers at the Iowa State Fair a few years ago, and beat some steers that had done well earlier but were not sound enough to suit him (some probably never were sound) and had a few people upset. My advice to them was to find a steer that could walk for the next year, since he would be judging that ISF as well!
