Kris sells lots of calves - because he usually sells good ones. There are never any guarantees, but he doesn't try to sell them unless he thinks they'll work for their intended purpose. A good friend of mine bought a calf 3 or 4 years ago about this time of year that went on to place well at Fort Worth in an exotic class. Kris's top end runs with anything and his cheaper calves usually do just fine. Lots of reasons for calves still being left over. Some lose their hair early and don't sell, some are too green early on, etc.
I bet you'll do just fine.
