Tony didnt run and he got wore down beat up and injured all in the safe pocket lol so I dont buy your argument.
I think the issue with Dak being a "running QB" is that instead of making him learn to sit in the pocket and learn to read defenses and master his footwork , you are basically giving up and saying that he will never learn.
As time goes by , his athleticism will deteriorate and you will be left with an unathletic QB that can't sit in the pocket.
Think of Dez Bryant and how once his athleticism left him he was done because he never learned the position.
Older QBs all stick around because of their mastery of the position.
If Dak doesn't learn how to be a pocket QB now , when will he?
Gimmick QBs don't amount to much.
The greatest QB to ever play the game (Brady) is a lanky , slow , statue... let that sink in.
Why can't defenses stop him or figure him out after 20 years in the league?
