MIAMI GARDENS, Fla., May 28 (UPI) -- Tua Tagovailoa and the Miami Dolphins coaching staff maintain a mutual understanding of their focus entering his sixth NFL season: "an expectation of a mastery of everything."

Dolphins coach Mike McDaniel spoke about Tagovailoa's off-season goals during the second day of organized team activities Wednesday in Miami Gardens, Fla.

"We already know he can do a lot of things throwing the football, but we are working on the craft of being a quarterback each and every play and continuing that process of development so he continues to be, on the field, a better version of himself than he was the year previous," McDaniel said.

Tagovailoa was among dozens of Dolphins to report to the voluntary sessions, which started Tuesday at Baptist Health Training Complex.

He is entering his fourth season under McDaniel.
