Start, sit? Drop, pick up

Should I drop Randall Cobb for Ted Ginn jr or Kenny Stills. I have Julio Jones, Doug Baldwin and Michael Crabtree.
Also start newton this week vs Tampa bay or Watson vs Seattle ?
Thanks

Personally I would drop Cobb for Stills, I trust Ginn more but looking at the stats, it seems like Stills is getting more targets. As far as your QB’s… Its tough but I would play Newton
