Whats up with Matt Cel having no luck in regards of starting all 16 regular season games since he became...?

...the full time starting QB for his own team and current team (KC Chiefs)? Expect for the season that he subbed in for injured Tom Brady and his previous team (NE Patriots). Mean that Cel was recovering from injury that he suffered in the preseason. Now, he is currently recovering from an emergency laparoscopic appendectomy, this past week (12/8). Which forced him to missed a game so far and maybe it means missing another game. Suspect that he will be playing in the last regular seasons game of this year and possible playoff game/s. If The Chiefs do win AFC West and make to playoffs, this year. Unsure how far they will go into the playoffs. Since they are still relative young and inexperience team at the moment. Of course they have veterans on the team as well.
