Warmsley's average gain would probably have made an even bigger impact had he not dropped the ball after 50% of his carries.
He only made 5 carries in total so it's hard to say if that yardage would hold up with more game time. Manu and Sia gave decent go forward too.
A big charge from Warmsley, with Sia and Manu following up, with quick play the balls could really put a team back on it's heels.
