If people don't quite understand mechanics, release point, etc., there is a simpler rule to use. It is called the 26-27-60 rule. If a QB scores 26 on the Wonderlic, starts 27 or more games in college and completes more than 60% of his passes, he stands a good chance of succeeding in the NFL.

There are exceptions of course but it is a decent predictor still. RG3 fits in there.
Another thing being missed by the haters is that intelligence plays a huge role in QB success and this is a kid who was an honor student in high school and graduated early from college, also with honors.
