Senior Bowl practices start this week, which means the 2020 NFL draft is just around the corner.

What is the Senior Bowl? It's an invite-only showcase event for the best upperclassman prospects in college football. NFL teams will descend on Mobile, Alabama, to watch practices and see these prospects compete against one another. There are three days of practice, including 90-minute sessions for each team on Tuesday, and two-hour sessions on Wednesday and Thursday.

Check out coverage of practice on Wednesday and Thursday at 1:30 p.m. ET on ESPNU/ESPN App. The game is Saturday at 2:30 p.m. ET on NFL Network.

Our NFL draft experts -- Todd McShay, Mel Kiper Jr. and Steve Muench -- pick the best and rising prospects you should know in Mobile.

McShay: What to watch for from the six quarterbacks

Even without Joe Burrow, this is a talented senior quarterback group heading to Mobile. Justin Herbert headlines the signal-caller roster as a potential early first-rounder, but the class also includes College Football Playoff semifinalist Jalen Hurts and Pac-12 record-holder in passing yards in a season Anthony Gordon. Here's what I want to see from each QB this week.

Justin Herbert, Oregon

Team: South | QB ranking: 3

Quite simply, Herbert is the best quarterback on the field at the Senior Bowl -- and he has to look the part. I'm watching for him to dominate after throwing for 3,471 yards and 32 touchdowns this season. The best players always find a way to stand out by the end of the week, and the 6-foot-6 quarterback needs to separate himself from the pack. Show off the big arm. Make some plays with that mobility. And find some rhythm and consistency throughout the week. Herbert has to make a statement.

Jordan Love, Utah State

Team: North | QB ranking: 6
