DAVIE, FL—Explaining that the rookie is shy and easily discouraged, Miami Dolphins coaches told reporters Thursday that they were having trouble getting wide receiver Andrell Smith to participate in practice. “Andrell is such a sweet kid and we’re trying to get him involved, but so far he hasn’t really come out of his shell,” said offensive coordinator Mike Sherman, noting that when a play starts, Smith usually just stands by himself near the sideline or runs off on his own without looking at the quarterback. “The trouble is, he’s too timid to call for the ball even when he’s open, and in the huddle he barely says a word. The only time I actually heard him talk was when he came up to me and quietly said he wanted to go home.” Sherman added that he and the other coaches also wanted to encourage young quarterback Ryan Tannehill to share better with receiver Mike Wallace.
