Personally, I think the Cheifs original version when Reid first took the HC spot it was him. He used some good players, a few rookies and a decent QB. He got fairly good results but not a SB or anything. Then, enter Bieniemy and Mahomes (and a few other young players) and KC is starting to look like the Patriots with Brady. Now, you have Andy and Mahomes...but you are missing the play caller...Bieniemy. Meaning that the team is learning a new system and the guy who WAS calling plays is gone. All the talk about who was call the plays Bieniemy or Andy...appears that it was indeed Bieniemy after all.
