Deeper QB streaming options?

12 team full ppr. Most teams have 2 QBs, so my options for Stafford’s bye are not giving me much confidence (especially after a 1-4 start and losing 3 straight weeks by 4 points or less). Any thoughts on the following options?:

Alex Smith vs Carolina
Joe Flacco @ Tennessee
Derek Carr vs Seattle
CJ Beathard @ GB

Am I crazy for leaning towards Beathard and stacking him with Morris? Any thoughts or advice would be much appreciated!
