Drain strawberries on paper towels; set aside. In a large bowl, combine flour, oats, brown sugar, baking soda and salt. Cut in butter until mixture resembles coarse crumbs. Reserve 1 1/2 cups for topping. Pat remaining crumb mixture into a greased 9-inch square baking pan. In a bowl, combine sugar and cinnamon; stir in strawberries. Spoon over the prepared crust. Sprinkle with the reserved crumb mixture. Bake at 350° for 35-40 minutes or until golden brown. Serve warm.
