A PBC will only be as great as its participants.
A PBC will only mean as much as people are willing to risk and make it mean.
Times are a changing and while it might not necessarily be for the worse PBC's are not what they used to be. PBC's should mainly be reserved for two instances, a divisional game and/or a game with huge implications. Non conference games should almost never be PBCed and I've seen a few this year. Thumbs down to that. Unless you have a very fitting and important reason to PBC one of those games I would tend to avoid that. I remember somebody made a PBC this year and I posted in there "Is there ANY reason this PBC could be meaningful?" I remember getting back something like the assistant QB coach of the Cowboys used to be a coach on the other team. That's not grounds for a PBC people! I try not to get into any confrontations around here but at times I've politely (Or maybe at times not so politely) questioned why a PBC was issued.
Here's an example of a very successful PBC this season: viewtopic.php?t=349034
What made that PBC great? BOLD predictions, things are needed to put on the line. Meaning behind a PBC is what makes it fun and too many times we've had lifeless PBC's. That PBC (Bears/Cowboys week 3) had plenty of meaning and in my opinion was an NFC superiority swinging game.
Wager the avatar, wear a sig of shame, go for a MONTH not just a week. Things like this provide great entertainment and make these things memorable. Take this from someone who's been a part of some of the most epic past PBC's.
I'm too lazy to run a few more searches but I'm thinking of a few right now that were unforgettable PBC's: Like Week 1 between the Colts and Ravens in 2005, Sunday Night Football, deluxe and Duran Duran had at it... Find that thread, I still use the Peyton Manning NASA picture in Del's milestone threads, even though he hates remembering that because the Ravens lost.
That's what makes this stuff so GREAT. If you can laugh and remember things years down the road, that's what makes a good PBC. That's what we need more of. Pictures, trashtalk, predictions, DO IT. Win or lose you'll make memories and keep this stuff great. Put your heart into it.
