He didn't define "need", but he and Lovie both said that because of the good players we have throughout the team, they didn't feel they were "held hostage" by a certain position they had to fill in the draft, so they took the guys they liked. They said these three players have some sort of intangible "competitiveness" that very few players in the draft had, and that no players left in the draft have because the Bears took the last three available. He said some people might think not taking a tight end is a "head scratcher" but since it isn't a need position, he decided not to take one because he is happy with the tight ends on the roster already.
