My guess is we were taking WR Greg Childs...
Watching the War Room it is my speculation that we were going to take WR Greg Childs.
The Packers had pick 132 and 133. After those picks the Cowboys got excited in the war room and the WR Coach was in the room shaking hands. Then the Vikings chose Greg Childs and all of a sudden the WR Coach was gone and Rob Ryan was in the room.
So I think we may have been primed to take Childs but the Vikings got him at 134 so we got S Matt Johnson instead.
Again, speculation on my part.
