Bucky Brooks says there are roughly 15 prospects with a first round grade this year. So that's pretty much the cut off point for a trade down scenario. Once you get beyond that, the drop off (talent) is quite significant, according to him.
I don't think they'll trade out. Because someone will fall to them. My bet is on Anderson, being the one.
Both Houston & Arizona are rumored to be in on Wilson. Arizona is also trying like mad to trade their pick. The Raiders are rumored to be that team that wants to acquire the 3rd pick. While the Colts are locked in on Levis.
That leaves you with...
1. Young
2. Wilson
3. Stroud (Trade)
4. Levis
The Hawks should have their pick of Anderson, Carter & Richardson.
If you believe the Matt Miller report from earlier in the week, then Anderson should be the pick.
