The Tennessee Titans season was an unmitigated disaster, and when you look at the 21 unrestricted free agents on the roster, there is much work to be done.

And those 21 don't even include players like Shonn Greene, Kamerion Wimbley, Bernard Pollard and perhaps Andy Levitre, who could be cap casualties the way Michael Oher was last week.

Of that list of 21 players, the Titans really should have two as the highest priority on their list. And it might not be the two you think.

Some might say the Titans should re-invest in old war horses like Michael Roos (if he doesn't retire), Nate Washington or George Wilson. But all three are past their prime and should only be brought back on a minimum deal, if at all, because they don't really fit as part of the rebuilding process.

Others believe the Titans should try to re-sign former first-round pick Derrick Morgan, who did a decent job in his first season as a 3-4 linebacker. But Morgan probably will look at the open market after the Titans dragged their feet on an extension, and truthfully, with Dick LeBeau coming in to run the 3-4 defense, Tennessee would probably be wiser to invest in players who are more natural fits in that scheme.

To put it bluntly, when you go 2-14, almost every spot on the roster is subject to upgrade, which should be the Titans approach this off-season to free agency and the draft. But among the players the Titans should make a priority to retain are two key special teamers.

Kicker Ryan Succop came to the Titans after being released by Kansas City, and though underused in his first season in Tennessee, Succop was reliable. He connected on 19 of 22 field goal tries (two of those misses actually came in the same game), meaning that most of the time Succop was automatic.

Last year, the Titans had released Rob Bironas and spent the entire summer and preseason auditioning possible replacements with no success. Succop fell into their laps and agreed to a one-year deal. The Titans shouldn't tempt fate again; they should lock up the kicker with a multi-year contract.

The other priority should be punter Brett Kern, who just completed his sixth season with the Titans and had the second-highest yards per punt average of his career with a 46.8 yard average, while punting a career-high 88 times.

As with the kicker spot, the Titans could gamble that a younger player could fill Kern's shoes, but again, why tempt fate? If Kern has done the job well – and he has – reward him with a new deal rather than gambling on the unknown.
