Good post. One thing about second base is that, while it's an up-the-middle position, it's also usually a dead-end position. While second is important defensively, if the player had better range, they'd be a shortstop. If they had an arm, they'd probably be a shortstop. If they had both, they'd be a good shortstop. Occasionally, you'll get a second baseman who can hit and has an arm but third basemen are hard to come by, too. If you have a shortstop with an arm and a bat, you probably don't move him to second base at all, but instead move him to third. There just aren't many examples of second basemen who ended up there despite their talent to play elsewhere.
