Krishner, the SDSU coach, didn't see it that way.
"I absolutely love the kid," Krishner told The Union-Tribune at the time Corona informed him of his decision. "He epitomizes everything we are looking for in a person in our program. We'd like to have him back."
And then there was the medical scare that helped steer Corona's decision.
His family was hit with some scary news. His sister became seriously ill and her survival was in doubt. She has since made a full recovery, and now attends Sweetwater High.
Then Corona dealt with the death of a dear friend who collapsed and died on the soccer field.
So, what was Corona to do?
He said his father suggested finding work in Mexico to try and ease financial burdens.
Playing for the Xolos was a sexy option.
Corona made the choice and played for the Xolo's third division squad before working his way up the ranks. He attended Southwestern College in Chula Vista. His time in school didn't last long. He stopped attending classes to focus on playing soccer.
"I plan to keep playing here and make it to first division," Corona said. "My sister and my family are happy to see me play here."
Corona has adjusted to the professional athlete lifestyle. He crosses the border throughout the week for practices and games on Sundays using the SENTRI fast- pass to avoid the long wait times.
He said he makes enough money to live comfortably and help his parents.
They will get to see he has begun to establish himself as a force on the Xolos lineup. Corona uses his crisp skills and uncanny feel for the game to help generate most of the team's attack.
He showed off some of those skills in the Xolo's 2-0 win in at Durango on Feb. 18. He scored his third career goal filtering through defenders before taking a point-blank shot at goal to send the ball into the net.
It is something the fans like to see. It detonates their chants.
"Corona! Corona!"
