I'm not involved in this PBC, but I was just looking through this thread and had to say something about this. I've seen this type of sentiment everywhere and it just seems like people don't read the articles they post sometimes.
Read the first paragraph above the picks. CBS staff picks against the spread. The expert picks from Sportsline is for gamblers, and NOT a prediction on which teams will win.
Anyways, about this PBC, not surprising no Titans fans took up the challenge. They might show up for a Houston matchup though.
