Harvard BS is probably super inflated in terms of how good they actually are at debate. Other college debaters used to say that their success was from the huge coaching structure Harvard had/has. Despite this, Bolman still did have a large amount of knowledge of psychoanalysis but outside of that, meh.
Personally, the best K team is probably Michigan KM or Loyola EM. They have a VERY unique style like being super trolly but still had the mechanics of debate DOWN. Both debaters had high levels of technical skills, argumentative breadth, and just in general debate sense. Loyola on the other hand quite literally invented our now kritik debating in terms of both style and the arguments themselves. Baudrillard, Bataille, Nietzsche and many others are all either Loyola creations or have been taken to a whole other level. Again, Loyola maintained high levels of technical skills and a humongous argumentative breadth. Another important fact is the fact that Loyola actually coached both BoSu and KM, which imo adds to their resume.
Another really really good team is UMKC AT. Despite having less argumentative breadth (not because they don't know the arguments, just their preference), they are incredibly technical and have definitely made the achievements. Finals of CEDA and Octas or quarters of the NDT? (personally think the round vs Rutgers was bs but whatever).
Conclusion: I think its Loyola cuz James is the best.
