Fantasy blockbuster trade

[eochs]

Trying to decide on this.

I give up:
Demarco Murray
Randall Cobb

I get:
Jamaal Charles
Andrew Luck

I'd be upgrading from Stafford/Flacco at QB. I also have Leveon Bell so I'd still be stacked at RB. Way deep at Wr also with Sammy Watkins, Ty Hilton, kelvin Benjamin, Odell Beckham jr, and Torrey smith. This goes along with Jimmy Graham at TE.

12 team league, PPR. 6 point pass TD. I had a very strong draft and both my rookie wr's have blown shit up.

Opinions? I may need to do a second Wr downgrade also (kelvin Benjamin for Marques Colton or somesuch to clinch the trade). I'm 6-2 and dominating the league in points scored. $500 to first place off a $50 buy in, $120 to second
