Robinson should have never been drafted.

1) Get a playmaker with a top 5 pick (Somebody who touches the ball or rushes the passer)
2) If you choose to go off #1 because it is somebody special, Orlando Pace, you better get a complete player versus a project

Projects in NFL (Not for Long), by the time the player is producing, the other good players around him are likely diminished because of age or injury or moved on because of salary cap reasons.

You can't stash a guy on the roster for years and get no value.
