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.

I'll have my updated Big Board and position rankings on ESPN.com later this week, but I wanted to take a few questions from readers about what I've seen so far. I'll start with a question about my top-ranked quarterback before the season, Oklahoma's Spencer Rattler, who was booed by his own fans on Saturday. A few more names I'll hit: Matt Corral, Derek Stingley Jr., Evan Neal and Kayvon Thibodeaux. (Questions have been edited for clarity.)

I also picked a prospect who is rising after Saturday's games, plus an under-the-radar prospect to keep an eye on throughout the rest of the season:
