In a vacuum, you retain Ragland. But that wasn't the case this summer. The reality is, whether it was the lingering effects of the injury or inability to grasp the defense, Ragland was 3rd string in camp and didn't even look good there. There's no doubt that Bills wanted him to do better because it doesn't look like they like P Brown either. Brown hasn't played well and Ragland is even worse than him in a 4-3.
What role would he play on this team, knowing that you wouldn't want him anywhere else but MLB, and he couldn't beat out Vallejo in camp?
