The NFC South side picked Mike Glennon in the third round of this year's draft, fueling speculation that Freeman could face competition for his place in the team.
The team's head coach told NFL Total Access: "We only have one. It's Josh Freeman. I believe in competition, and Mike Glennon is going to be a tremendous quarterback in his time, but we have a quarterback, it's Josh Freeman.
"He had a really good spring. I think it's really coming together, being in this system for a second year now and hearing the things over again after being able to study it, I'm really encouraged.
"I know Mike Sullivan, our offensive coordinator, he's encouraged. We're looking forward to big things. Josh is going to have a big year."
Freeman completed over 4,000 passing yards in 2012, but threw 17 interceptions.
