DAVIE, Fla. -- The Miami Dolphins completed their second session of organized team activities that was open to the media.

Here are some interesting developments and observations:

Dolphins No. 1 receiver Mike Wallace lit up practice Monday. He had three touchdowns in team drills and each was of a different variety. Wallace caught his trademark deep ball from quarterback Ryan Tannehill for approximately a 40-yard touchdown to get things going. Then, Wallace also caught a skinny post over the middle for a touchdown and another score in the corner of the end zone on a broken play. Both of those touchdown passes also were from Tannehill. Wallace is being moved around this year and there are early signs of success. “Nobody can have a key on me,” Wallace explained. “Last year ... it was every game in the same spot. When you move around, it's hard for a defense to know where you're at.”

As Wallace’s stats can attest, it was a much better day overall from Tannehill. Last week, Tannehill struggled with his accuracy and overall command of the offense. This week he was more consistent. Tannehill made quick decisions, his throws had zips and it led to big passing plays. He did throw one interception to safety Jimmy Wilson, but the pass was initially dropped and wasn’t Tannehill’s fault.

It’s early June, but Dolphins tailback Knowshon Moreno doesn’t look game ready. He’s currently working as a backup behind starter Lamar Miller and didn’t look sharp at OTAs. Moreno also looks a little thicker than usual. Philbin was asked Monday about Moreno’s conditioning. “I think my instincts tell me for this time of the year it’s pretty good,” Philbin said. “But I think there is certainly some room [for improvement] as we get rolling.”

One other standout in Monday’s practice was defensive tackle Randy Starks. He applied good pressure on the quarterback and schooled new Miami starting guard Shelley Smith several times.
