Spring training doesn't matter, so they say. And they're mostly right ... mostly.

But you know, it's not always so cut and dried. For players on the bubble, spring performance means a heck of a lot, and not every spring development is tied to performance anyway. The exhibition season represents our first look at players who've been working on themselves for four months -- maybe longer for the ones that didn't get to play minor-league ball last year -- and the adjustments they've made, as well as what their team has to say about those adjustments, can tell us a lot, particularly when the performance backs it up.

As long as you're careful not to turn your rankings upside-down, reading concern into players that have no reason for any, there's no harm in following along with what happens in spring training -- again, particularly for players on the fringes.

Or you can just let me summarize it for you with these 20 winners and then, uh ... five losers. I was planning on going 10 and 10, but I guess I just like to keep things positive.
