There's no stopping it now. The seeds have already been planted. All that's needed now is for Josh Freeman to throw one interception — or maybe just one bad pass — and a Buccaneers quarterback controversy will begin to grow.

No matter how big or small it becomes, the quarterback on the other end of this inevitable ensuing debate is ready. Mike Glennon has been through this before.

Oh, has he ever been through this before.

It was the spring of 2011. North Carolina State coach Tom O'Brien was over quarterback Russell Wilson's dalliance with baseball, so he decided to release him from the team, knowing he had Glennon waiting in the wings.

Talk about being thrust into a tough spot. Wilson was coming off a year in which he had guided N.C. State to a 9-4 season (its best in five years) and had led the ACC in passing yards per game (274.1) and total yards per game (307.5).

But O'Brien believed the Wolfpack would be better off with Glennon running the offense for two years than it would be with Wilson running it for one, and despite the angst his decision generated, he might have been right.

While Wilson was finishing off his college career at Wisconsin and starting what is already a notable pro career with the Seattle Seahawks, Glennon was producing in two years the kind of stats that Wilson produced in three.

For example, the 7,085 yards Glennon threw for during the 2011 and 2012 seasons rank fourth all time in N.C. State annals, right behind the 8,545 yards that Wilson produced as State's starter from 2008-10.

Glennon also finished his Wolfpack career ranked fourth behind Wilson in school history with 1,069 career pass attempts, third behind Wilson with 646 career completions and third behind Wilson with 63 career touchdown passes.

You see those numbers and you can see not only why the Bucs spent a third-round pick in last week's NFL draft on Glennon, but how that decision could easily develop into a full-blown quarterback controversy.

Though the Bucs have made it clear that Freeman is their starter, Glennon's history suggests he could do the same thing for them that Wilson did for the Seahawks, which is take over as a starter and lead them to the playoffs.

“Look, if something were to happen to Josh Freeman, we want to have a chance to keep the season rolling and going, and we feel like Mike's got the talent and the ability to do that,” Bucs general manager Mark Dominik said.
