That's a fair question. Orndorff is a Top-10 guy, but you're talking about a group of pretty clear Top 5 guys. It's a good bet that Steveson (Minn.) would have won the NCAA tournament this year, Parris (Michigan) was right behind him and Cassioppi (Iowa) slotted in right behind him.
Kerkvliet at Penn State is the wild card of the bunch. He and Steveson scrapped in high school, but we don't know how he'll fare against the rest of the schedule yet - it's Penn State, so you assume he'll be a world-beater, of course.
But here's the rest of the story: it's not just about how he stacks up against those guys, but how far he can advance in the Tournament. You're going from Gas Tank Gary (my favorite guy on the roster) who was a guy "nobody wanted to face in the Bloodround," to a guy who was slated to be an All American. So when looking at the team race, that's an improvement that matters.
