The Tennessee Titans did not waste any time getting busy once NFL free agency began, first agreeing to a deal with premier guard Andy Levitre, then swiping versatile tight end Delanie Walker from San Francisco.

The latter will sign a four-year deal in Tennessee, per ESPN's Adam Schefter, though no financial details have been released yet.

The Titans no doubt want Walker to help lessen the blow of Jared Cook's impending departure. Walker is not the pass-catching threat that Cook is -- the former had just 21 grabs in 2012 -- but he is a very reliable blocker.

San Francisco utilized Walker in a variety of roles, especially once Colin Kaepernick took over at QB and opened up the playbook.

In Walker and Levitre the Titans already have added two very steady players up front.

Grade: B.
