With all the speculation about Drew wearing his arm out I decided to look a little deeper at the closest comparison I could think of. A Major League Pitcher. What I have not and pretty much can't be accurately accounted for are non game throws, toll of hits on a QB, or the effort used to throw.. QBs don't always throw 45 yard passes and Pitchers do not always throw a fastball.
A NFL regulation football weighs 14-15 ozs.
A MLB regulation baseball weighs roughly 5 ozs.

QB - In Drew's career he has thrown 6,276 passes in games. Ave of 33.3 Att/game.

Pitcher - James Shields For the Royals has thrown 3,559 pitches so far this season. A MLB pitcher ave 147 pitches in a game.

So a ball park (excuse the pun) assumption would be that a pitcher in 1 season throws as many times as an NFL QB does in 6 seasons... Add a toll for weight differential and a SWAG knocking that down to 2 years.

Injury aside, I don't see that Drew is over throwing his arm. That injury may be taking its toll though, there is some loss of velocity as I have seen him under throw as many as everyone has but then again some times he is spot on with his pass.

At the end of the day I have proven nothing and you just lost 4 minutes of your life. However this could be worthy of discussion for those that have played both QB and pitcher.
