By JOHN HENRY To use an idiom, you might say Zuela Adom has gone the extra mile to compete in college athletics.That’s also literal. She’s actually gone extra miles. North and south on Interstate 45, back west on Interstate 20 and finally north on I-35 to Edmond, Okla., where the former Euless Trinity star has found a volleyball home at Central Oklahoma.And the Bronchos have found a very nice player for their volleyball program."I wanted to come in and help the team out as much as I could, whether I was playing or on the bench," said Adom, a junior transfer from Houston.
