Even the NFL's best teams aren't perfect. Inevitably, just about every squad is going to get found out. Take last season, when the Giants blew up the Vikings' pass coverage to upset them in the wild-card round.
The Eagles were able to overpower the Giants up front to blow them out in the divisional round. Three weeks later, in Super Bowl LVII, the Chiefs used the threat of jet sweeps and Philadelphia's struggles dealing with motion to score two key touchdowns and knock off the Eagles.
Some flaws become apparent as the season goes along. Others seem obvious before the season even begins. Based on what we saw last season and the changes each team made this offseason, we're going to identify a potential problem with each playoff contender and rank them from most concerning to least concerning.
Defining «playoff contender» is a tricky proposition. There are 14 teams in the AFC that could credibly call themselves playoff contenders right now.
