Hard to say without knowing what was going on behind the scenes.
Did he go pass heavy because the turf was making a ground game impossible?
Were all those unproductive passes to Gurley in the flat by design or check down?
Were the unsuccessful because of the turf?
Why didn't we challenge the endzone in the 2 minute drill instead of that (ultimately incomplete) swing pass to Gurley?
Why didn't we go to a hurry up offense sooner when we were having trouble finding our rhythm?
Glad you mentioned the refs though. Donald was held all game by the same tactic they flagged Havenstein for. Goff obviously passed to Watkins because he saw the defender holding him. Assisting a runner is a 10 yard penalty.
