The Chiefs are not going to draft anything other than a quarterback. Even if they don't want to, they know the p.r. implications of drafting any other position. A quarterback will satiate fans for a few years and will generate fan interest and attendance.
Selecting the #1 pick is as much about business as it is football.
In the final seven games of the 2013 season, the Chiefs averaged 34.6 points per game, scored 38 points or more 4 times, and went 2-5. The NFL has ruined the sport.
