RIZ,
Thanks for the question. There is no requirement to make a pick every day in the POD. You may not have a best bet, but have other games you do like. You can post them in the area that fits the sport in topics below the POD.
As for cash, the cash won in the POD is off your picks, and others. There is a lot of cappers that you should follow, and some that you may want to fade (like me <img border="0" title="" alt="[Smile]" src="images/icons/smile.gif" /> )
Keep on posting, and tear the roof off.
