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 for the kicker who signed a four-year extension to sputter out over the course of the year 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.
