Another TE thought for Chicago

Since the Chicago Bears made the decision to go with Marc Trestman as their HC, it's been rumored that the team would also be investing in the TE position this offseason, as their incumbent options don't really have the skills to play the role as it will be played in Trestman's offense. As a result, any of the high-profile TEs set to hit the market have been linked to the Bears, but there's a good chance that they won't get a chance at them, given the possibility of franchise-tagging (or re-signing) by other teams. So who will they add?
