This seems so simple. If you can't find a safe receiver, you can run it or you can avoid the interception and the sack. More than a few times at Denver, he got the ball to receivers who then muffed it badly.
Sometimes the receiver blows it. Happens for all QBs. And sometimes the QB wisely throws it away. But Tebow often just blew it, missing receivers by whole yards. He’s just not accurate with his throws.
