If third-year center Bismack Biyombo feels threatened by the Charlotte Bobcats adding big men Al Jefferson and Cody Zeller you wouldn’t know it from his approach.

Biyombo started 80 of 82 games last season averaging 4.8 points and 7.2 rebounds. After the season the Bobcats used the fourth pick on Zeller and signed Jefferson to a 3-year $40.5 million contract.

Biyombo likely isn’t starting this season but he doesn’t see himself as extraneous.

“My job is the same as it was last year – be a defender protect the paint rebound block shots. Nothing is going to change” Biyombo said after the first practice of training camp at UNC Asheville.

The Bobcats drafted Biyombo seventh overall in 2011. He’s a long athlete and tough guy but he arrived in Charlotte from the Spanish League with minimal offensive skill. That hasn’t changed much.

New coach Steve Clifford has told Biyombo not to fret about what he can’t yet do.

“We talked about that – to keep it simple do what you do best and help the team however you can” Biyombo said. “There’s no pressure and that gave me time to work on my game. If I’m here then I’m here for a reason.”

Jefferson is a premier low-post scorer but not a great defender so there’s a contrast in strengths between Jefferson and Biyombo. Zeller will likely be used more as a power forward than a center.

In Patrick Ewing the Bobcats now have a former superstar center on the coaching staff. Biyombo Ewing will be of great value to his development.

“(Ewing is) very helpful. We talk a lot about the game.” Biyombo said. “We work out all the time together – before the others and after the others. He’s going to make me a lot better.”
