Dak Prescott

There's an un-written rule in sports.... 'You can't lose your job due to injury'.  But what would (should) you do if you were the Dallas Cowboys??  Rookie Dak Prescott has been playing 'well beyond expectations' during the first 5 weeks of the season.  Hypothetically speaking, If veteran Tony Romo is ready to play next week,... Should the Dallas Cowboys pull Dak Prescott out of the starting lineup for Romo?  or should they stay with the rookie while he's still on a 'roll'?

I want to hear your thoughts.........
