I honestly did not see that one coming. Takes one guy off my list that I would have thought to have been available.
Cook was going to force them to tag him as a WR if the decided to use the tag. Based on his being predominately lined up in the slot and not as a TE. Had the tried to tag him as a TE, there was going to be a big dispute with the NFLPA that Tennessee probably just decided to avoid.
Here's a link for the latest on who got tagged: http://www.nfl.com/news/story/0ap1000000146745/article/deadline-day-tracking-franchise-tags
