Just a speculation play. I have been buying them up and I am tapped out of coins now. Invested X-Factor DL as most GT will have two 0 AP slots and I saw several Cornerbacks and Safeties and no DL as Golden Tickets. After someone assembles a secondary with the Golden Ticker secondary players, they may be willing to spend 1 AP on the DL X-Factor cards. Same with if someone gets all the GT WR and buy Gus The Bus, but there are more secondary GT if I am not mistaken so DL X-Factor is the safer investment.  If they do not skyrocket (I think they will), you can quicksell these for training and roll TVP.. Prices bottomed due to this being overlooked by any MUT player left. Buy while prices are down. 

Straight hustlin'

Let the pump begin.

Youre welcome.
