Tebowing might be seen as a parody by many people, but as Tim Tebow recently told the Denver Post, he's OK with it all and has even heard nice stories about it:
"It's not my job to see peoples' reasons behind it, but I know (of a kid) with cancer that tweeted me, 'Tebowing while I'm chemoing' — how cool is that?" Tebow said. "That's worth it right now. If that gives him any encouragement or puts a smile on his face, or gives him encouragement to pray, that's completely awesome."
This has now basically become Tebow's trademark in the NFL, but it's not as though he purposely set out to do it. As he is quoted at the end of the article, this is a "serious" thing for him, because he really is bending a knee and praying. There's nothing wrong with that, even if some might imitate in order to make a joke.
The kid who does it while having chemotherapy is just one example of the positives we should be taking from Tebow. What's the point of putting him down for maybe not being a good quarterback (still undecided on that) or for being outspoken about his Christian faith? He really is someone kids should follow in example.
