As the Broncos continue to grind through the NFL Draft meetings as the selection weekend approaches, they have largely done what work in free agency they're going to do until they see how their draft class shakes out. But the question of whether or not they have repaired their biggest dilemma on defense is still indeed a question that will need some attention among their current slate of six picks later this month. Until the meltdown against the Ravens in the double-overtime loss in the playoffs — 31 points and 479 yards allowed on defense to go with one sack on Ravens quarterback Joe Flacco — the Broncos had shown immense improvement on that side of the ball compared to any and all of their recent seasons. But the one problem that vexed them plenty, especially when offenses pushed them into the nickel (five defensive backs), was when the ball went to opposing tight ends and running backs in the passing game. A quick review of the damage: • Opposing tight ends and running backs caught 153 passes for 1,407 yards and 14 touchdowns combined against the Broncos defense this past season. Those totals accounted for 47.7 percent of the receptions the team allowed, 39.5 percent of the passing yardage and 56 percent of the passing touchdowns. • The opposing tight ends alone accounted for 81 receptions for 948 yards and 11 touchdowns.
