Bleacher Report

The last game of the 2018-19 NCAA season was on January 7. The draft doesn't start until the evening of April 25. This year's crop of draft hopefuls hasn't played a meaningful down of football in the time in between, but mock drafts and big boards will change roughly 3,283 times during that span. Prospects naturally move up and down draft boards as teams further study film and evaluate All-Star games, the combine and pro-day performances. The biggest catalyst for changing the draft picture, though, is free agency. As an example, just consider the fact that the Jacksonville Jaguars' signing of Nick Foles to a four-year, $88 million contract takes them out of the quarterback market in Round 1.
