When you put it that way, then you are clearer, but I do think "xe'u di
voi nanmu" is clearer then "xe'u le nanmu".  Unless the non-veridicality
of "nanmu" is critical here, though, "xe'u nanmu" does the job.

No, it doesn't.

I had to think about this a bit.  I think the answer is

	le ka da poi se bende be xe'u de gi'e kelcnraninbeka cu sutra
	the property-of (X which is-a-team-member of Y and is-a-running-back)

where X is a purely local variable, but Y is the lambdacated one.
In symbolic English that is:

	being a y such that(there exists x : x is a team-member of y & x is a
		running back & x is fast)

This assumes that the place structure of "kelcnraninbeka" is just "x1 is
a running back".  If it's "x1 is a running back for team x2" then we
can get rid of the explicit "se bende" in favor of:

	le ka da poi kelcnraninbeka xe'u de cu sutra
	the property-of-being-Y such-that-the-X who is-a-running-back-for Y
		is fast.

or in notation:

	being a y such that (there exists X: X is a running back for Y &
		X is fast)
