The Bears can’t seem to find and retain quality tight ends. Regardless of how you feel about the individual trades, the reality is that both Greg Olsen and Martellus Bennett played well on the Bears and then went on to play well on their new teams (in the case of the former, Olsen has proven steady and reliable; in the case of the former, Bennett is on his fifth team in ten years). In the meantime, the Bears have seen the services of players like Khari Lee, Kellen Davis, and Zach Miller.
