Here is an example of what I will be dealing with:
"""
TOTAL FIRST DOWNS                                     19        21
   By Rushing                                         11         6
   By Passing                                          6        10
   By Penalty                                          2         5
THIRD DOWN EFFICIENCY                           4-11-36%  6-14-43%
FOURTH DOWN EFFICIENCY                            0-1-0%    0-0-0%
TOTAL NET YARDS                                      379       271
   Total Offensive Plays (inc. times thrown passing)  58        63
   Average gain per offensive play                   6.5       4.3
NET YARDS RUSHING                                    264       115
"""

I can only hope that they were nice and put a leading zero in front of
numbers less than 1.
