Here's the deal with the recruiting board...
We toyed with the idea of doing it by position, but decided against it because there are many players who play mutiple positions (such as OL-DL or WR-DB). It just seemed like it would be a way to miss a guy because we had him at the wrong position.
We could maybe employ some sort of searchable databse in the future, but that's why we went with alphabetical this time.
Until then, you can always search a position by hitting "Ctrl-F" and do a manual search.
