"So much about the Bucs remains a mystery, even as draft preparations start to ramp up with this week's Senior Bowl.

The team has yet to hire a coach. Even when it does, it will remain unclear what type of defense it will employ until a staff is in place.

But this much is unequivocal: The Bucs' defensive performance in 2011 can't be repeated if a turnaround is in the team's future.

In their effort to improve their 30th-ranked defense, don't be surprised if Tampa Bay embarks on a search for more playmaking from its linebackers, a position that was under great scrutiny during the season.

One possible source: April's draft, where some candidates will be available, including some participating in this week's senior showcase."
