In so many ways it seemed like last year all over again for Buccaneers quarterback Mike Glennon. There he was Sunday, seven seconds left in the fourth quarter, down by four, his team deteriorating around him — just as it did much of last season.

The difference is this time the tall, rangy kid with the ability to spin one of the tightest spirals you’ll ever see brought the Bucs back. And not just from behind, but from the brink of oblivion.

When Glennon hit Vincent Jackson with the 5-yard touchdown pass that gave them an improbable 27-24 comeback victory over the Steelers at Heinz Field, the Bucs were staring straight into the teeth of a second straight winless September.

Now, even at 1-3, they’re just one game behind the NFC South division leading Falcons and Panthers, both of whom are 2-2. That’s how quickly fortunes can change in the NFL, and the feeling inside the Bucs locker room is that fortunes are indeed changing.

“I definitely believe in momentum,’’ said Lovie Smith, who won for the first time as Bucs coach. “Sometimes nothing good happens until you get that momentum and find a way to win and you see what it’s like to win. You have to experience it first.

“Until today, we didn’t know how to win. Today we found a way, and this is just a step. We talk about quarters and this was the last game of the first quarter (of the season) and to finish off with a win like that was big, because we needed to play better than we have been and we did.’’

What the Bucs needed more than anything going into this game was better play from their quarterback. Josh McCown played well at times before spraining his right throwing thumb in a loss to the Falcons last week, but wasn’t making big plays or good decisions.

That all changed with Glennon in charge. Though the second-year pro completed just 21 of 42 passes, he gobbled up 302 yards with his completions and threw two touchdown passes against one interception while taking just one sack.
