Dallas caught all three of his targets for 27 yards and returned two kicks for 73 yards in Saturday's preseason loss to the Broncos.
Dallas didn't run the ball at all, but he showed flashes as a pass catcher and returner. The Seahawks likely won't provide Dallas with much backfield work as long as both Chris Carson and Rashaad Penny are healthy. However, Dallas' impact on special teams -- he blocked a punt Saturday as well -- and his receiving abilities make him a strong candidate for the No. 3 role. Alex Collins and Travis Homer (calf) are his primary competition.
