Alexander Mattison will soon make a great contribution to the success of the Vikings, despite his slow start and yesterday's fumble. Jefferson got a pass for his fumble through the end zone, but some small minded fans have chosen to attack Mattison for his equally effort intensive mistake. Dalvin Cook and Adrian Peterson fumbled often without being subject to the excoriation Alexander Mattison unfairly received. Support Alexander's effort. He will reward you for doing so. If the OL gives him any sort of hole to run through, he will excel.
