Time for Titans to turn to defense

NASHVILLE, Tenn. -- The Tennessee Titans made just two picks in the first two days of the NFL draft.

Tackle Taylor Lewan and running back Bishop Sankey should help fortify the offense.

But the Titans won't add a defender until at least the fourth round, when the Titans hold picks 112 and 122. They also have 151 in the fifth, 186 in the sixth and 228 in the seventh.

The Titans have reasonably good numbers on the defensive line and at linebacker. But young talent suited for the new 3-4 is hardly in abundance and is something I expect them to address.

The Titans can use cornerback depth and a young safety to be groomed for a spot where their top three are aging.

They need a fourth receiver who can graduate to a top three spot in a year and could take a tight end to compete with Taylor Thompson for the No. 3 spot behind Delanie Walker and Craig Stevens.

Quarterbacks in the second half of the draft rarely pan out, but Zach Mettenberger or Aaron Murray could be intriguing and have more value than the average late quarterback because they may go later than they would if they weren't coming off ACL reconstructions.

They are likely to wait to find competition for Maikon Bonani at placekicker until after the draft is over.
