Saints first round questionnaire - Your best guess / best case / worst case

Assuming we stay at No. 24 in the first round of the draft, list the following:

1. The one prospect that is your best guess for who we select at No. 24
2. The one prospect that is your favorite pick for us at No. 24 (with reasonable chance of being there aka no top 10)
3. The one prospect that is your worst pick for us at No. 24

Lastly if we were to trade up, what is your best guess for who we trade up for?
