Costanzo adds to talented special teams

SANTA CLARA, Calif. -- Blake Costanzo is reuniting with several key figures from his NFL career.

The special team ace re-signed with the San Francisco 49ers on Tuesday. He was a star on special teams for the franchise in 2011. Not only is he back with several coaches and teammates from his first go around with the 49ers, but he is back with other people who he is close with. Fellow special teams ace Bubba Ventrone and Costanzo are close friends from their days with the Jets in 2006.

Costanzo, who was with the Bears last year, played for 49ers' special teams coach Brad Seely in Cleveland. They remain close.

"I text Seely all the time just to bust his chops," Costanzo said. "Whether it was about football, or just busting his chops about life in general. But I was in contact with him for sure."

The 49ers are stacked with solid special teamers such as Ventrone, Kassim Osgood and C.J. Spillman.

While a lot will shake out in training camp, there is a chance not all of the top special teamers will make the 53-man roster because of number's game.

For example, Osgood could have difficulty if Brandon Lloyd continues to shine at receiver. Lloyd has little chance of being the No. 3 receiver, but if he is a solid No. 4, Osgood could be pushed out.
