Not a lot of certainty on Bucs' offense

TAMPA, Fla. -- New Tampa Bay Buccaneers coach Lovie Smith comes from a defensive background. But Smith and the new general manager are going to have to spend the majority of their offseason building the offense.

With the exception of adding a pass-rusher, I don’t see a lot of big needs on defense. I look at the offense, however, and see needs just about everywhere.

There are only three or four sure things on offense. Doug Martin is set at running back, and Vincent Jackson and Mike Williams are set as the wide receivers, although the Bucs would be wise to add some depth at receiver. You might be able to include guard Carl Nicks on this list, but only if he’s fully recovered from a bout with MRSA and a toe injury that kept him out most of last season.

Aside from those three or four spots, nothing is a given. Smith had some praise for quarterback Mike Glennon at his introductory news conference. But Smith stopped well short of saying Glennon will be his starting quarterback.

I liked some of what I saw out of Glennon in his rookie season, and think he could be good with a strong supporting cast. But, at this point, I think the Bucs should at least bring in someone to compete with Glennon.

Speaking of competition, the Bucs need to add some at tight end. They might have stumbled onto something with Tim Wright, but they still need a blocking tight end.

Speaking of blocking, I don’t know that any spot is safe on the offensive line. That unit did not play well last season, and several offensive linemen are carrying large salary-cap figures.

The bottom line is that Tampa Bay’s offense is going to look a lot different than last season, when Williams and Martin missed most of the season with injuries. That won’t be a bad thing.
