You are wrong. The article does not refute that argument because (2) is about exactly the large dimensions of types of talent demanded. (Since universities want a variety of things)
You are assuming the consequent that there is not a large variety of things a university wants.
Saying if you relax a problem, it is easier, is not an argument that it can be relaxed. That is your fundamental misunderstanding. For the university, they do really find value in the things they select for with 2, so they have a lot of valuable candidates, and so picking a mixture of valuable candidates with a large supply of hard to compare offerings is in fact difficult, and will leave any one metric too weak for their preferences.
