From a points perspective I believe he will most likely outscore Kaepernick who I am starting over him. The reasoning, my SB opponent has both Crabtree and Vernon D. Sound logic?
No. If you think Cousins will score more then you start Cousins. Crabtree and VD don't matter.
1) You are talking about giving up points. To what, equalize the game? You don't want equal. You want more points.
2) WRs typically get rewarded at a higher rate than QBs for production. There is a good chance that Crabtree and VD account for a lot of Kaepernick's production. So you stand to be on the losing end of that combination.
Start Cousins if you think he will score more points. Who will score more should be your biggest priority.
I understand the reasoning here. My question is if there is any merit in hedging vs your opponents players? For what it's worth in my league QB's are as valuable as any position, 6pts per td and very good yardage bonuses. If Crabtree and Vernon go off I am almost guaranteed to keep close with Kaep. And I really like the matchup for Kaep vs Atlanta.
