This is my picks on the rest of the games for SD and KC.

 I would of done  Denver too but I don't see them competing with us for playoffs after glancing at their schedule.

 At least one or two of  these games I would pick us to win but I'm trying to go off worse case senerio.

wk.
5.  KC @ IND   {loss 3-1}               5.  SD @ OAK   {win 3-2}

{gut feeling we will split IND,HOU.  but going worst case}

6.  KC @ HOU  {loss 3-2}              6.  SD @ STL  {win 4-2}

7.  JAC @ KC  {win 4-2}               7.  NE @ SD  {loss 4-3}    
                       
SD has to loose at least one home game so I picked this one.

8.  BUF @ KC  {win 5-2}             8.  TEN @ SD  {win  5-3}

9.  KC @ OAK  {win 6-2}            9.  SD @ HOU  {loss 5-4}

10.  KC @ DEN  (loss 6-3)          10.  bye

11.  ARI @ KC  (win 7-3)            11.  DEN @ SD (win 6-4)

12.  KC @ SEA (loss 7-4)           12.  SD @ IND  (loss 6-5)

13.  DEN @ KC  (win 8-4)           13.  OAK @ SD (win 7-5)

14.  KC @ SD   (loss 8-5)            14.  KC @ SD  (win 8-5)

15.  KC @ STL  (win 9-5)            15.  SF @ SD  (win 9-5)

16.  TEN @ KC  (win 10-5)          16.  SD @ CIN  (loss 9-6)
                                                            primetime game ^^^^

17.  OAK @ KC  (win 11-5)         17.  SD @ DEN  (loss 9-7)

I think best case senerio for  KC is 11-5.  Worst case is 10-6.  If I were to change one it would be a kc loss to OAK or @ STL....one of the two. 

Best case senerio for SD is 10-6.  Worst is 9-7.  If I were to change one of them it would be a win @ cin.

Either way chiefs win AFC West and MAKE PLAYOFFS!!!!           GO CHIEFS!!!!
