Bradley gears up for baseball draft
Monday, Broken Arrow right-handed pitcher Archie Bradley likely will go early in the first round of the Amateur Baseball Draft, which will diminish the chances he makes it to OU.
ESPN projects that Bradley, who boasts a fastball that's topped 100 mph, will be taken seventh overall by the Arizona Diamondbacks. Baseball America has him going ninth to the Chicago Cubs.
Bradley signed with OU to play baseball but was planning to walk-on to the football team, too, as a quarterback. Bradley was invited to the prestigious Elite 11 quarterback camp last summer and had a stellar showing.
Because of his option to go to OU, Bradley has the luxury of a potentially high price tag. But any franchise that spends a precious first-round pick on Bradley will probably meet that price.
Metoyer still working to get qualified
Five-star wideout Trey Metoyer won't be one of the freshmen to report for summer camp this week. Metoyer is still working to qualify and won't be able to enroll until he raises his standardized test.
Metoyer, rated the No. 1 wideout in the nation by Scout.com, is one of the highest-rated players to commit to OU in the Bob Stoops era.
