It doesnt matter what kind of QB it is.
I have a list of attributes starting with the most important:
1.Play knowledge/Learning- The better the QB knows the play, the better the result
2.Toughness/Injury/Health-The higher each of these are the better. Lets fact it, a QB is going to take some hits, right? He has to be tough game to game to maintain his position as leader of that offense.
3.Awarness- The QB has to be aware of all situations. Pressure, open WR, mis-matches, throwing the ball quick enough to avoid a sack
4. Here is where Throw power, and accuracy comes in. the #4 most important thing. The best QB's in the league or in history have the above 3 qualities 1st. Those really matter.
5. Everything else after throw power/accuracy, is good, its like adding sprinkles to a cup cake. It makes it better. You get what im saying.
