The Bears may have picked up their best receiving threat from the Tight End position since Greg Olsen, but that doesn't mean they still aren't still looking to add another play making Tight End in the draft.
Michael C Wright from ESPN Chicago. reported earlier this month that the Bears were showing a legitimate interest in Stanford Tight End, Zach Ertz. Ertz is only one of the Tight Ends on the list of players the Bears have met with pre-draft. A list that includes athletic Colorado Tight End Nick Kasa, as well as the big bodied Kevin Milton from LA Monroe.
Each of these players bring a different style of play to what the well-rounded Martellus Bennett, brings. They are a more athletic breed, more in the mold of Jermaine Gresham and Jermichael Finley, as opposed to the traditional style of Tight End that Martellus can be compared to. In other words, they'd compliment the newly acquired Bear quite well.
