Is it possible for a guy to be too nice?

Here are two ways that this could ring true:
1: He's So Nice, He Can Only Be a Friend
Hey, a good friend is hard to find. What sometimes happens when we get into a relationship? It eventually runs its course and ends, which means awkwardness and/or change in both of you, since you started off as friends. Maybe you can recover and remain buddies, but is it worth the risk if you find that you're really good friends with a nice guy? Also, sometimes the nice guy just has no edge, so he's destined to be just a friend.
2: He's So Nice, He's Not Challenging Enough
I've recently learned from your comments: Women enjoy the thrill of the chase a bit too much. People like to wonder what's going to happen, that nerve-racking first few months when the "training wheels" are still on the relationship. And, no matter how much we try to deny it, we do like that we've won someone over instead of just having them give themselves up to us. If a guy is too easy, he may be ruining his chances.
