Fantasy Impact: The Packers' playoffs hopes are barely alive as it is, and if Flynn can't pull out a win against the Cowboys, there's a very real chance that Rodgers won't play another snap in 2013. With nothing to play for, Green Bay would likely opt to protect its franchise quarterback.
Flynn does not provide owners with a ton of fantasy upside. In his three games with the Packers this year, he's averaged 205 yards passing and has two touchdowns matched by two interceptions and lost three fumbles. Nothing about his play gives reason for higher hopes.
The only appealing aspect of Flynn's Week 15 situation is that he's taking on the Cowboys, who give up the most fantasy points to quarterbacks in the NFL. While that may have been enough for a spot start earlier in the season, Flynn still shouldn't be trusted in league semifinals. Owners in two-quarterback leagues could justify a start but standard leagues owners should stay away. He remains a bottom-barrel QB2.
