if your talking about sets w/ the rookies & everything, be ready to refund your sets because the top rookies aren't that easy to come by. my opinion is you'd be lucky to finish 1 set out of a case. I had to buy an absolute "TON" of retail to even get close to a set. platinum was the same way, I opened a case and know for a fact I was missing the Rg3 rookie from the set, I didn't even bother to try the set with the case, but cards were definately missing.
