4-4-2: Spencer's formation of choice

The season is just over a month away and the roster is almost completely set. Of course there is still the possibility of adding a few more pieces or dropping a few of the newer players. For the most part the Timbers have the core of their starting line-up signed. With all the changes to the roster will John Spencer go away from the 4-4-2 formation or will he go with a different formation?
