The more that I study this draft and the possible prospects that could be available for the Dallas Cowboys at 28, the more I like the idea of trading down. Of course, that’s easier said than done. But, for this 2017 Cowboys mock draft I decided to lay out the scenario that the San Francisco 49ers wanted to move up in the first round to 28 in order to acquire a quarterback so they can could take advantage of the fifth year option first-round draft picks receive.
