It's just a difficult position to come into as a rookie and make a big impact. I don't think people outside the game appreciate the difficulty involved. I mean, you can talk about the speed of the game, and how different it is, but there are a lot of other things that contribute to the problems players have at the position. It's a very steep learning curve, and it takes some guys a year or two to overcome it. It's a very short list of guys who come in and make an immediate difference at the position.
