Not too many teams you can go to where you'll be a legend and gainfully employed once you leave.
If Micah is concerned about his earning potential AFTER football, he would want to stay with the Cowboys, ESPECIALLY, if he wins a Super Bowl.
Look at Darryl Johnston
... Troy Aikman
... Tony Romo
... Michael Irvin
... Nate Newton
... Emmitt Smith
... Darren Woodson
... Roger Staubach
and several other Cowboys who got chances to shine (financially and with endless opportunities) beyond their playing days.
Besides, Jerry Jones is FIERCELY loyal to his former stars. He takes care of them beyond football.
Sorry, but Dan Quinn doesn't have the same financial and popular cachet.
