From the Pittsburgh Post Gazette:
The starting receiver opposite Antonio Brown for the first practice session was Markus Wheaton, the third-round draft pick last year. "There are a lot of us chasing that spot," Wheaton said. "It’s not mine. There’s a lot of good competition."… Roethlisberger said the implementation of the no-huddle offense, which was so successful in the second half of last season, will be up to Wheaton and receiver Lance Moore because they will have to be up to speed with the rest of the offense.
