Based on all I've seen and heard, the vibe I'm getting with 15 days to go are...
Setting the stage:
Clowney and Mack are surely going in the top 3.
The first QB taken can go anywhere from #1 to the middle of the first round.
The Rams will take Clowney if he's there at #2, otherwise they have a deal in place with Atlanta for Mack.
At #6, the Rams will hope at least one of the 2 top OTs are there, and that no team trades up ahead of them causing both OTs to be gone. If both OTs are gone, then I think the Rams trade down again from #6, just like 2012.
The Rams aren't taking Watkins even if he's there at #6. They will use him as bait and trade down instead, probably with Detroit.
There will be multiple trades in the top 10 of this draft.
My best guess at this point is... The Rams will end up with Clowney at #2, or Robinson/Matthews at #6 plus Atlanta picks, or player X at #10 plus a boat load of picks.
