DraftTrek is one of the more unique mock draft websites out there.
It uses math and computers and other geeky things that I'm sure are very interesting for people who know how to use them.
But I will say this, it's the most creative mock draft I've ever seen and will certainly keep me coming back for updates.
On the other hand, I can't say I agree with all of it.
But who really does agree with everything in a mock draft anyway?
