"Carradine's weight hovered around 300 pounds to take on the demands of being a 3-4 defensive lineman. Now, he is down to 270 pounds, which is closer to his ideal playing weight. Carradine does not have a contract for next season, but he made it clear he wants to return and make a mark under the direction of a coaching staff that has finally figured out how to utilize his style of play.
"I want to be here. I love it here," Carradine said. "But I don't know what's going to happen. I've only played five games this year and I didn't get to show a whole lot.
"But, hopefully, I can finish strong these last couple of games and come back next year and play because I love this scheme. I'd love to come back next year and play for the 49ers. If not, I have to move on and try to go to a team with a scheme that fits me."

I hope they resign him...the best teams don't just have 4 great starters but a whole stable of guys to rotate in and out. Tank could be one of those guys easy.
