Example: At least Raheem Morris finally has the name of the Bucs' starting quarterback in the back of his mind.
 He wants to make sure he made the decision with his head and not just his heart.
 That's why Morris declined to name his choice between Byron Leftwich and Luke McCown on Friday until after one last consultation with his coaching staff.
 After that  Morris said  he would inform the owners  then his team before making the eagerly awaited announcement. Players were off Friday  so an announcement could come this morning.
 "We'll have a decision here in the near future " Morris said. "I think we've got to go with who we think gives us the best chance to win.
Output: Raheem Morris
Here the main entity is Raheem  Morris since the main topic of the document is about him starting as quarterback.

New input case for you: Broward County police admitted that even more warning flags were missed that could have prevented  the horrible shooting by Nikolas Cruz at a Florida high school .
The Miami Herald reports that a tipster called the Broward Sheriffâs Office warning them that  Cruz  âcould be a school shooter in the making.â Deputies neglected to write up the warning in a report.
Two weeks prior to that tip being called in  a relative of  Cruz  also told police that they should seize his weapons.
Astoundingly  a third report was missed when two years before  the shooting a deputy  investigated a warning about  Cruz  saying  he  âplanned to shoot up the school.â
Output:
Nikolas Cruz
