You could set up a DEF/FWD loop with Dewar and Caleb Daniel, effectively giving you cover between two positions.
Could also consider Himmelberg, store up some extra cash for injury or sideways trades coming down the stretch of the season.
Then you can switch between Dewar and your F7/D7 in Daniel/Himmelberg and set up loops if you think one of your defenders/forwards have a tougher matchup.
West Coast have a good remaining chunk of their games on late Sunday so I'd be strongly be looking at DEF/FWD option for two line cover and loops (never know when you might pull off a good one).
