DAVIE, Fla. -

When it comes to taking advantage of Mike Wallace's speed, the Miami Dolphins need to make strides.

Little progress has been evident in training camp, but quarterback Ryan Tannehill is confident he'll hit Wallace on long passes more often this year.

Wallace ranks among the fastest players in the NFL, but he was often only a decoy last season, his first with the Dolphins. They targeted him on 34 passes thrown more than 20 yards, and only six were completed -- 18 percent.

When Wallace was open deep, Tannehill frequently underthrew him, and the result was an incompletion or interception. After the season, Wallace estimated he should have scored at least 15 more touchdowns.

Instead he scored five times and averaged 12.7 yards per catch, both career lows.
