No NFL team manages to fill all of its holes during the offseason. Each has a weak point or two that gets revealed by injuries or disappointing play over the course of a season. Even the most successful offseasons of 2018 prove that point. The Bears surrounded Mitchell Trubisky with talent, acquired a dominant pass-rusher in Khalil Mack and won the NFC North, only to see the kicker who signed a four-year extension sputter out and collapse at the worst possible moment. The Colts needed to turn to midseason acquisition Dontrelle Inman when their wideouts were struggling to stay healthy.
