Dallas has two meaningless regular season games left.  Avoiding playoff-impacting injuries should be top priority.   

Tennessee quarterback Marcus Mariota broke his leg Saturday.  The Titans loss to Jacksonville that day officially ended their playoff chances.  Oakland won on Saturday against Indianapolis, guaranteeing the Raiders a spot in the playoffs.  However, Oakland quarterback Derek Carr also suffered a season-ending broken leg in that victory, likely making the Raiders candidates for a quick playoff exit.  Which begs the question for Cowboys fans:  why take any chances?  Dallas plays Detroit tonight, then finishes the regular season New Years Day in Philadelphia.  First place in the NFC East is clinched, as is the #1 seed in the NFC side of the upcoming playoffs.  Smart money says the Cowboys should play it ultra-safe, sitting Dak Prescott & the rest of the starting lineup for most, if not all, of the next two games.  A couple weeks ago there was a clamoring for Tony Romo to lead the offense.  Now would be the time to let that happen.  Will owner Jerry Jones & Coach Jason Garrett take that approach?  We'll all find out soon enough!
