The overall most valuable and sought after football card singles this year will be in 2014 Flawless Football. It is likely the most valuable single Rookie Card will be the Topps Chrome or Bowman Chrome Superfractor. However, the 191 Autographed Rookie Cards for each of the 19 (Carlos Hyde autographs did not make it into the product) Rookies (a total of 3629 cards or about 1.4 cards per box) in Flawless will be very valuable and highly sought.
The twenty jewel embedded (numbered to 20, 5 and 1) Rookie Cards with no autographs could prove to be the most valuable cards for the 2014 Rookies. The 2012-13 Kyrie Irving Diamond RC (no autograph) #d 3/20 recently sold on eBay for $3250. The 1/1 Diamond should be worth much more. Manziel, Bortles, Bridgewater and Clowney 1/1 Diamond RCs will each be valued in the thousands.
2014 Flawless Football gives you 7 Autographs, 2 Game Used Jersey Patches and 1 Jewel Embedded Base Card per brief case box. The following analysis is based on my estimates of what the average box of 2014 Flawless Football will give you. If you don't like my values, use your own estimates for average value and see what you get. In any case, 2014 Flawless Football is an outstanding value.

AVERAGE DOLLARS PER BOX 1263
The "Average Dollar Value Per Box" of $1263 indicates if you open enough boxes you should average nearly the cost of the box. There will be some winners and some that don't do nearly as well. Boxes are hand-packed by Panini, so no box will be too bad. In any case, 2014 Flawless Football gives you more for your money than any football product to date.
