Whatever has been said about Tim Tebow and the attention he gets or his ability to stick in the NFL, he has never given anyone reason to say anything bad about him as a person.
Tebow is an inspiration to many people. He has many, many fans, many of which might not even be University of Florida (or Denver Broncos, or New York Jets, or New England Patriots, or Philadelphia Eagles) fans but root for him anyway. And he does great work through the Tim Tebow Foundation.
Even though Tebow doesn't currently have a job in the NFL after being cut by the Eagles at the end of preseason, he can have a great effect on people who need it.
