Tebow has shown very poor judgement all around, from refusing to consider a change of position to stay in the NFL, to making a baseball bid late in the year instead of early in the year so he could have had minor league ABs. He’ll be 30 years old before the next minor league season is over.
If someone doesn't want to be an accountant, he shouldn't be an accountant - even if newspaper readers that live across town thinks he should.
He is within his rights to refuse the position change and live with the consequences. As for baseball, he knows the odds are long, but he wanted to try it. I'm sure the timing was based on when he decided to try and how long it took to prepare. When he was ready, he asked if anyone was interested. It would have been great if he tried three years ago, but he didn't get the bug until recently.
