Dolphins WR Roberto Wallace has stood out during offseason practices. "Roberto is going to be a pretty good receiver in this league," David Garrard said. "When he puts it all together, he can be a big talent." Signed as undrafted free agent in 2010, Wallace has impressive size and speed, but has been mostly limited to special teams work so far. He has a chance to earn plenty of reps in the Dolphins underwhelming wide receiver unit.
