Idk if he initially collected as well as people hoped. If true, I imagine the spring sample size of the 1OAK offspring isn't as large as some would expect. In other words you will see some this fall but probably not enough to form to much of an opinion on him yet.
Once the fall sales start you should see some, it’s probably more of guys not wanting to show them off because then they’re locked in to a date of birth. Hard to show off a newborn in January and claim it’s a mid March with an 85 lb birthweight. Plus the flushes would have been a little late last year, you’ll see a lot of embryo calves next year. Should be worth the wait.
