"you could do a better job of convincing me that you understand my background and skill-set; I see you even are advertising for NMS positions on your company's site."
I had a similar experience, and because I had multiple people from their office call me about different positions in the same time period, I became convinced that recruiters are just allotted a concrete list of positions that _they_ are responsible for. (think of it like randomly handing out a different list of target customers to each member of your sales team)
Even if you aren't a good fit for a given position, they'll call you about that position and not the one you're a better fit for, because well, it's not _their_ job to fill the other role.
I've always mentally associatted third-party recruiters with 'Glengarry Glen Ross,' so the idea that there are a number of 'leads' they all fight over would make sense. Just reversed with the easy to fill jobs being the good 'leads'. Some of the third party groups I've dealt with certainly had that aroma. (Some of the megaCo recruiting depts, too.)
That's exactly what happens at some places, from what I've heard. In some companies (the more commission-oriented ones) employees even own their "contact list" of candidates.
