Please don't misunderstand me. But your comment seems to be lacking intellect of a certain degree. Why would a Dolphins fan pay attention to what Caddy does? I mean, I understand about looking at some highlights and stats but thats about it. I don't see your logic.
Second, your statement about "there is a reason why he was the starter and Brown backed him up you know" clearly has no meaning. Ryan Leaf was a starter in college too. What a player does in college is just that and only that, its college. Also, both players have different olines, different coaches, different offensive plays, etc. So your attempt to compare the two is on a very very narrow edge. If you are unable to compare RB's at least have the common sense to look at what you can compare. Such as running styles, blocking abilities in the backfield, etc.
And if you'd like to play like the ignorant media and just say stat 1 vs stat 2, then also look at injuries. Caddy is a rookie and already has been held out 1 game in the first 5 games. Using that logic, he's going to miss at least 3 games this season. Doesn't make sense does it?
