I have a link to Donruss in the right hand column so you can check this out for yourself, or you can follow the direct links: 2006 2007 2008
Looking at their releases, what the hell is the difference in their Football products? They have: Playoff Prestige, Donruss Elite, Donruss Classics, Donruss Threads, Playoff Absolute, Donruss Leaf Certified Materials, Donruss Gridiron Gear, Donruss Leaf Limited, Donruss Leaf Rookies & Stars, and a box set of Donruss Playoff NFL Rookies.
That is 9 releases not counting the box set. What is the point? The products are at very similar price points with Limited being $10 a pack, Absolute at $40, Certified Materials at $10 and the others at 4-6. Is there really any difference between the jersey, patch, and auto cards?
At least with Topps there is some difference: Finest, Chrome, Base, Sterling, still too many sets, but whatever.
