FRISCO -- Wide receivers coach Sanjay Lal expressed disappointment with some of his young receivers after two preseason games. Outside of Tavon Austin, Randall Cobb, Michael Gallup and Cooper, there is some uncertainty over who makes the team at wide receiver. Devin Smith and Cedrick Wilson, two veterans, have surged past some younger receivers."I'm going to be harsh on the lower guys but they're making it hard on themselves," Lal said.
