re: Rivals.com reporting Maurice Williams switching from LSU to Houston

The word was still used incorrectly as you likely suspected.

[Utmost means “greatest” or “highest,” as in “utmost importance” or “utmost respect.” Upmost is less common synonym of uppermost, meaning “at the top” or “highest in position,” as in “upmost layer.” Though the words are similar and can overlap in meaning, upmost is an error when used to mean “greatest.”]
