Starks saw action at that position as a backup in 2008 and at times last season.
"When he was in there, he was very good," Ireland said. "He's got the body type to play the nose."
Starks is listed at 6-3, 305 pounds, but Ireland said he didn't think Starks needed to add more weight to play nose tackle.
Ireland also said that Starks was on board with the plan.
"The quote he gave Coach (Tony Sparano) is, 'I'm at home in there,' " Ireland said.
According to Ireland, the Dolphins came to the decision to move Starks long before the draft and that the selection of Penn State defensive lineman Jared Odrick was made with it in mind.
Under the Dolphins' plan, Starks will move inside and Odrick will replace Starks at right end.
Paul Soliai, a fourth-round pick in 2007, started four games at nose tackle late in the season after Ferguson sustained a season-ending quad injury, but Ireland said he "would assume" that Starks will be the starter at nose tackle.
