Maurice Jones-Drew announced his retirement from the NFL on Thursday by posting a message on Twitter saying that “all good things come to an end.” In his note on the matter, Jones-Drew called his 9-year playing career an “amazing” time and said he is looking forward to the next chapter of his life. Jones-Drew was a powerhouse type running back just a few seasons ago, but injuries, contract disputes and a lackluster season with the Oakland Raiders last year slowed down his momentum. He never looked right in the black & silver of the Raiders and he likely wasn’t going to be much of a factor moving forward anyway.
