St Pat's start early this year? About to begin myself. Then it will all make sense ... 1 bottomless bloody at a time.
What I'm trying to present to you is that the Chiefs broke their 20+ playoff drought by NOT flipping over the table after losing in the playoffs in 2014, in Reid's second year. They stayed the course, and got everyone on the same page. From 2015 on, they've been a powerhouse, even before Mahomes.
