Denver Broncos quarterback Tim Tebow is an unconventional leader who's likely to quote scripture in the locker room.

The focus should be on the workforce or the team, and what they perceive. Because if they don't perceive the right thing in a leader, you're through," says Robert Hogan, a research psychologist.
