Monty has pointed that team names are restricted to colors or anything that can remind ones of colors (like Ruby is red gemstone, Coffee is commonly brown colored drink, Sun is usually depicted in yellow). Also, if situation calls for it, using the initial of the last name is highly probable, such as team CRDL, where L stands for Lark instead of Sky from Sky Lark. The chance is higher than just combination of four letters, then.

Though, I've faced similar problem creating my own team which somewhat in the end ended as MJAW for Macaw (a name of bird). Nonetheless, in the end I changed their name again to suit their original theme.
