Interesting stats about Jacoby from Bill Barnwell of FO. Following is copied from Paul Kuharsky's blog post (The original article is insider's only).
On Jones, Barnwell writes:
“…He was a legitimate go-to guy when teams were tripling Andre Johnson and daring Matt Schaub to throw somewhere else. Schaub threw Jones 13 passes on third down; Jones caught 10 of them, gaining 125 yards and seven first downs.”
So more than a third of JJ's receptions came in a third down situation. Not exactly what you expect from someone who is seen only as a deep threat.
