The Bears' signing of unrestricted free agent tight end Michael Gaines could present last year's fifth-round pick, Kellen Davis, with an uphill battle for a roster spot this year. The 6-foot-7, 262-pound Davis played in all 16 games last season as the No. 3 tight end but did not catch a pass and was a marginal contributor on special teams. With Greg Olsen and Desmond Clark doing most, if not all, of the pass-catching at the tight end position, the Bears want their No. 3 tight end to be a powerful blocker which is Gaines' forte.
