Some pretty big free agents are hitting the market this offseason, and one of them is long-time Pittsburgh Steelers defensive lineman Brett Keisel. It seems as though Keisel is nearing the end of his career, but the Pro Bowler says he's not done yet and still has something left in the tank. He also mentioned he wouldn't mind continuing his career by signing with the Detroit Lions. Keisel's first choice would be to return to the Steelers, as they're the only franchise he's ever known. But if he can't return, Detroit might want to phone him up rather quickly after he hits the market. Source: FanSided
