It looks like Adam Schefter just tweeted that both Jacobs & Waller are going to play on Sunday. Do you play them if they suit up against a great Pats D(16th against RB, 3rd against TE)?
Jacobs should be in your lineup but knowing that he may not see the volume he has been getting this week.
For Waller, if you cant get a streaming TE (Schultz/Sample/Thomas) then Waller is starting as well.
Overall, unless your team loaded, you will most likely be starting them.
