That is basically closing a small hole by tearing open a huge crater next to 
it. For it begs the question: if this is correct, why did the K-Pg impact(s) 
have such a marginal impact? 

It practically *forces* special pleading (namely that Chicxulub was in some way 
"different" from all other large bolide impacts), and this is not a good way to 
start.
