NASHVILLE, Tenn. — Titans coach Mike Mularkey believes Marcus Mariota got a very important reminder that taking a sack is much better than turning the ball over.

For the quarterback, it was a painful lesson not to do too much.

Mariota’s second NFL season started much differently than his first with two crucial turnovers returned for touchdowns, and now the quarterback taken No. 2 overall in the 2015 draft has to show he can make better decisions with the ball when Tennessee visits Detroit on Sunday.

Mularkey said the quarterback did a good job in the first half of Tennessee’s 25-16 loss to Minnesota in getting rid of the ball when plays broke down, something he’s seen a lot from Mariota.

“I think that’s a thing you won’t see again from him,” Mularkey said Wednesday. “Not a lot of mistakes after doing it one time.”

Mariota was under pressure when he threw the ball to Vikings linebacker Eric Kendricks, who ran 77 yards for a TD. Mariota and DeMarco Murray messed up a handoff with the quarterback trying to pull the ball back, leading to Danielle Hunter’s 24-yard fumble return for the second TD.

Mularkey said he doesn’t want to restrict Mariota because the quarterback can make some great plays too. In preparing for the Lions, Mariota got a reminder of quarterbacks taking a sack and moving onto the next play.

“Those are some of the decisions I’ve always kind of prided myself on,” Mariota said.

The quarterback’s day wasn’t all bad. Mariota helped the Titans take a 10-0 lead into halftime and finished throwing for %href_on(file:
