We already knew the Buccaneers would have a new look on defense. They’re going with the Tampa 2 system.

But this defense also will have a new sound. That’s because someone different will be calling the defensive plays. Middle linebacker Mason Foster now will fill that role. Weakside linebacker Lavonte David wore the radio helmet and called the plays the last two season. But Foster has called the defensive plays in the past.

“I did it my rookie year and we had a lockout that year,” Foster said. “I’m used to it. It’ll be a smooth transition. Real smooth.’’

The switch is being made because coach Lovie Smith prefers to have his middle linebacker calling the plays. That likely means the Bucs are counting on Foster to be an every-down linebacker.

That could be a challenge because Foster hasn’t had to spend a lot of time in pass coverage in the past. But he’ll be asked to do that in this scheme.

Can Foster handle the increase in pass coverage? Smith must think so or else he wouldn’t be giving Foster the radio helmet.
