We just need the Chiefs to lose another game and beat them ourselves in our matchup to gain the tie breaker. I for one think it's doable. As I would hope that the Chargers can get past them for once and think they can with a healthy Ekeler.
You run it on first down to keep the opponent from rushing free to your QB and it opens things up for play action etc. Toss in if do it enough you can tire a defense out.
