I think this is a very nice steer for your first show steer. If he classifies american in this slick show then I think he has plenty of style and type. Hard to tell if he has enough ear to classify from this pic though? He does have a bit more leather up front than most of the people on here are used to(you dont see many american type cattle on here) but I actually think he is fairly clean for an American steer. He is a little heavy fronted, my guess would be he was left a bull a little to long, that tends to make those front ends get a little coarser, but I dont think its a deal breaker for this steer. While he does look a little tight flanked in this pic, you have to remember that he is standing a little stretched which will suck that flank up and he is also still pretty green. I would expect him to deepen in the flank as he grows and finishes which will make him balance up a lot more from end to end. He looks pretty wide based, has some shape to the hip, and looks to be good topped. Like someone said earlier its hard to find a hole in this steer and in my opinion the only one I really see at this point is his front end, but I dont know that will be a problem down the road.
If he has enough ear and classifies American then I actually could see this steer being competitive depending on how big and competitive your show is. If he ends up having to little ear to classify American then it will be a little tougher for him to compete. But all in all a very nice steer to feed for your first year. What county are you showing in?
