NASHVILLE, Tenn. >> Marcus Mariota never had to worry about huddling up to call plays at Oregon — he and the Ducks simply glanced to the sideline for what to run next.

Now with the Tennessee Titans, it’s up to Mariota to huddle up his teammates and call a play only he has received from the sideline. The play can be as short as three words or as long as 11.

So the Heisman Trophy winner says he’s practicing those calls every night on his own to make sure he’s ready to rattle off whatever coach Ken Whisenhunt wants.

Mariota showed his command of the huddle Tuesday as the Titans took the field for their first organized workout this offseason. Whisenhunt says that hasn’t been an issue since Mariota arrived as the No. 2 pick overall.
