I'm not buying it. I think the key to maintaining and extending Tebow's mystique and appeal is to compete at all times. Always compete. Compete and do your best, and it will always be enough. Always compete, and show that you love to compete. So said Coach Pete Carroll on 710AM radio every day for the past 2 years. Never back down. Retreat is not an option. This in keeping with Touchdown Tim's personality, or at least the personality I am familiar with. You can't hurt yourself by competing and refusing to retreat.
All we need to see is that some improvement in your mechanics has taken place. Even if it is just a little, the critics will see that you are working on it, and you are getting better. That is all it will take. Then you can go into your pro day knowing you have not passed on any opportunities to impress.
I just don't think Tebow should chicken out like Clausen and Bradford. He should do what his buddy Colt McCoy is doing. Always compete.
