You obviously have never been a athlete in where you are a large part of the teams strategy and success. Any athlete would tell you they would want to stay in the game in Tebows position. He wants to be on the field when the clock ticks down to 0:00 in the 4th.
and u havent been in the position to make tens of millions by not doing someting stupid that doesnt affect the outcome of the game since it is decided already....
