In 2014, the Kansas City Chiefs were the second most stingy passing defense in the entire NFL, giving up just 3,252 yards in their 16 regular season games.
In 2015, however, the Arrowhead Stadium franchise have been torched for 861 yards already and we haven't even made it to week four.
And the Chiefs have been handed a big blow to their attempts to turn around their regressing secondary today, with the news that starting left cornerback Phillip Gaines is out for the season.

As reported by NFL Media's Ian Rapoport, Gaines will miss the rest of the 2015 campaign with a torn ACL. The nickel corner suffered the injury during Kansas City's Monday night defeat against the Packers.
Moving forward without the third-round pick of the 2014 draft, the AFC West franchise have been further exposed at a position that was already causing them problems.
The man who replaced Gaines on Monday Night Football, rookie Tyvon Branch, was picked apart by Aaron Rodgers.
Of course, the Chiefs won't come up against a MVP-calibre quarterback every week, but their faith in Branch stepping in for Gaines will have been shaken by his performance.
After missing the opening game of the season, Gaines had registered si combined tackles in the last two weeks, to go alongside the 20 he made in 13 appearances for the Chiefs in 2014.
