"Carries inside the five" pops an error:

/usr/local/lib/python3.6/dist-packages/ipykernel_launcher.py:3: UserWarning: Boolean Series key will be reindexed to match DataFrame index.
This is separate from the ipykernel package so we can avoid doing imports until

I think the lines

inside_5 = data[ (data.yardline_100<5) & (df.play_type=='run') ]

should read

inside_5 = df[ (df.yardline_100<5) & (df.play_type=='run') ]
