TAMPA, Fla. -- The Tampa Bay Buccaneers' most glaring weakness is at offensive guard, but coach Lovie Smith said the team is close to settling on the starters for the offensive line.

"Last week I had a frown on my face when I was talking," Smith said Sunday. "I'm not frowning right now.

"We made progress from last week, and that's what we wanted to see. We wanted to see progress in all areas. Everybody wants to talk about the offensive line. We're concerned about it and other positions, too. The offensive line got better last night."

Specifically, the new guard tandem of Oniel Cousins and Patrick Omameh held up well enough for 22 plays Saturday to allow quarterback Josh McCown time to complete five of seven passes for 46 yards, including a touchdown toss to wide receiver Vincent Jackson. The offensive line also blocked well enough for running back Doug Martin to rush six times for 24 yards.

"I thought the group held their own and we saw improvement," Smith said. "But as I said all along, our plan is to let everybody have an opportunity one way or another as we go through.

"When you get to the third preseason game, you're getting ready for the season, and the group we put out there right now, they earned that right to get the majority of the plays this week. It will all be fairly clear on what we're thinking this week."

Though he didn't discuss the players who were off Sunday, Smith stopped just short of saying the Bucs plan to stick with Cousins at left guard and Omameh at right guard.

With the starters expected to play into the third quarter of Saturday's game at Buffalo, it will essentially serve as the final dress rehearsal this preseason for the No. 1 offense. Few, if any starters are expected to play in the preseason finale against the Washington Redskins on Aug. 28 at Raymond James Stadium.

"We had some guys who played better than others," Smith said of the offensive line. "Anthony Collins played well. Evan Dietrich-Smith. Demar (Dotson) didn't play as well as he played last week. Patrick Omameh did a good job for his first time out."

In fact, Smith felt good enough about his starting guards that he offered no evidence for changing that combination this week.

On Omameh, an undrafted free agent from Michigan was who signed by the Bucs off the 49ers' practice squad last Oct. 11, Smith said, "I think he held up. And when I say played well, I'm talking about all the things we ask him to do. Inside, you've got to be able to one-on-one block versus the run, versus the pass. Our quarterbacks, we held a couple balls, but for the most part protection gave them time to hit the receivers. Patrick was a part of that.

"Last week, the guards were at the top of our minds because of that constant, quick pressure inside. And he didn't really allow that. That's his first time out. We'll just kind of continue. If he's in there -- you were kind of leading me down that road -- we'll see how he does."

Cousins, who is entering his seventh pro season and has five career starts, would seem to have his position locked up.

"For Oniel to be in there two weeks, that's telling you I think we know what he is for the most part," Smith said. "Played solid ball."

NOTES: Tim Wright switched positions from wide receiver to tight end as a rookie last year and finished second on the club in receptions (54), receiving yards (571) touchdowns (five). This preseason, however, quarterbacks can't find him, and he is in danger of disappearing from the roster. Wright played only 17 offensive snaps Saturday in the Buccaneers' 20-14 preseason loss to the Miami Dolphins. He was targeted twice, catching one pass for 5 yards. ... DL Gerald McCoy continued his dominant play. McCoy had three tackles -- two for losses -- and a quarterback hurry in his limited action, but he came up with the first splash play of the preseason when he nabbed Miami QB Ryan Tannehill and forced a fumble that DE Michael Johnson recovered. The takeaway set up a Tampa Bay touchdown.
