Who to sell before BLITZ Promo?

Hey. I was wondering who to sell high on before Blitz, with hopes I can buy them back cheaper later this week, or next week. I didn't know if there was a position specifically that typically goes down, or should I just be selling all of these guys for now? or sit still? I have 1. mill currently.

My offense has 

-93 Randy Moss, 93 barry, 93 hester, 92 tyreek, 92 pitts, and 93 RG3

Defense has

-93 simmons, 93 taylor, 93 parsons, 92 ramsey, 93 ed too tall

Thanks for any help!

I'd sell all of them. They will drop in price a lot when Blitz drops

Just remember you might have to be QUICK when rebuying

Any set cards will depreciate in value.  So basically everyone you have listed.  I have sold some of them off but I have kept some of my favorites like Moss, Rodgers, Simmons, Parsons, and Ramsey.  I could probably make 100k profit on each by selling and buying back but I also want to win some h2h and Champions games before Friday., so Ill take the slight lose.  Ive also liquidated everything else 89 and above in my binder last week so Im sitting on over 4 mil.  I think selling also depends on your coin stack and what cards you want to buy during blitz.  Are you going to buy back all the guys listed or would you make improvements if newer cards come out?
