No - you are missing the point sorry to say.
That article in no way "proves" that NFL teams are ignoring "better" talent for the sake of savings. If anything, it's quotes from two guys with a vested interest in seeing the UFL succeed talking up their league. Can't blame them, but it doesn't mean NFL teams are knowingly ignoring veterans who could make their teams better simply to save a few bucks.
The article actually goes so far as to cite the points spread as proof that the Bills are closer to a UFL team (by the way - as bad as the Bills are, do you think any UFL team could go into Foxboro and come as close as the Bills did? Laughable.). The lack of sound reasoning to make an illogical point is astounding.
edit - Yeah there might be some talent in the UFL, I'm not denying that, but you are talking 1 or 2 players per team, not an entire roster.
