To paraphrase Coach, "Maroney was what he was." He wasn't Curtis Martin nor even was he Corey, but he was a decent--not spectacular--NFL RB.
However, Maroney was saddled with high expectations from the beginning. Remember when Shanahan said that Laurence was going to be a major NFL star? I recall watching his NCAA clips after he was drafted and thinking, "Wow, how did that guy fall to us?"
For whatever reason, he wasn't able to take the daily pounding that an RB takes in the NFL, including, it seems, on the practice field. I defended him many times out here, but now I join with those who say it's time to move on, both in terms of our thoughts and expectations as well as practically. It's a damn shame, since we didn't need to lose both our QB and our "top" running threat in two months. Also a shame because we have other holes to fill in the Draft and Free Agency after we used a Number One on an RB so recently.
The only consolation is that with the (at least temporary) end of the Cap, Bob Kraft will be one of the few NFL owners who, if he wants to, will be able to open his wallet to pick up someone strong.
