I talk a lot about the importance of considering the versatility of a suit as well as being creative when it comes to breaking it into separates. If you're going to invest in something, you should get more than your money's worth. However, there are times when no matter how creative you are, a suit jacket as a separate just doesn't quite hit the mark. It could be that the fabric won't blend with more casual fabrics like cotton or denim, or that it's simply too formal looking to be dressed down. Enter the sport coat.
