The chances of a quarterback making even one All-Pro first team is just 4.6%; a 1:25 shot. However, that chance more than doubles when selecting a signal-caller in the first round (9.4%) and rises to 11.9% if the player is selected in the top five.
Think about that.
If you are taking a quarterback, and you determine there is one available in the top five who fits your criteria, you have turned your chance of landing one of the top passers in the game from a Hail Mary to a long-third down conversion. It's still tough, but there is a much higher probability.
Not every quarterback is going to be an All-Pro. And failing to achieve that doesn't mean you aren't a franchise quarterback. So let's lower the standard to Pro Bowlers.
