We're through four weeks of the college football season, which means it's time to reset what we know and don't know about the 2022 NFL draft. When I did my preseason rankings earlier this month, I noted all of the changes that were likely to come this fall. That's because this is such a crucial evaluation period for underclassmen and seniors; games matter, and what happens in them far exceeds the importance of the hype off the field. So far, we've seen a few risers, fallers and surprises from the top of my Big Board, along with a couple of notable injuries.
