I've long compared to mocking Round 1 of the NFL Draft to building a puzzle.
When you take all of the pieces out of the box, you're left with thousands of scattered pieces all over the table. Some are face down, and some fall off. But you don't just pick up one piece and go from there.
For the NFL Draft, you don't start at No. 1 and go to 32. The draft is unpredictable, and no one will have a perfect mock.
Like a complicated puzzle, though, there's a way to build a strong mock. Once you flip all the pieces over and get them together, you see the bigger picture.
