Near earth Asteroids and a space elevator

Ok so this is silly and purely hypothetical...

I am under the impression that should we ever decide to construct a space elevator we would need a pretty large mass on the space side of things. and that is one of the hurtles to making one.

I am wondering if we have the capability to "catch" one of these near earth asteroids. i guess we would not have to use it for a space elevator a bunch of studies could be done with just an asteroid in oribit. but the space elevator was what prompted the thought.

Capturing an asteroid in earth orbit would be difficult, holding it stable in a fixed distance - priceless.

If you read a publication such as this one released by NASA:
you'll find out that the question of capturing an asteroid is skimmed over, with a suggestion that it is both feasible, not yet developed(as of 2000) and probably less interesting/daunting than other hurdles that need to be overcome.

This 2011 article from National Space Society, talked at length about the guts of asteroid capture:

And sure enough, this year the Keck Institute for Space Studies at Caltech published this feasibility study:

But the space elevator doesn't need the counterweight to be anything more than an additional length of cable dangling out from the far end. This publication mentions such a variant:
