Dan Marino doesn't think it would be a bad idea for the Dolphins to draft a quarterback this year.

Marino, speaking Saturday at the Dan Marino Foundation WalkAbout Autism at Sun Life Stadium, didn't endorse the idea. But he said depth is important at every position, especially quarterback.

"I don't know if the Dolphins are going do that," Marino said of drafting a quarterback. "But you do have to look at the way the league is now, there's injuries and you do have to have solid players and solid people at each position, especially at quarterback, if something happens to your starter."

Rookie starter Ryan Tannehill had mixed results last season in his first year as the Dolphins' starting quarterback. He finished with 12 touchdowns and 13 interceptions while completing 58.3 percent of his passes (tied for 22nd). His passer rating of 76.1 ranked 27th in the NFL. It should be noted Indianapolis quarterback Andrew Luck ranked 26th with a passer rating of 76.5.

Still, there's a feeling in some circles that the Dolphins need an insurance policy at quarterback, in case Tannehill starts wandering down the Chad Henne path of malaise/regression.
