My QBs and RBs in a non PPR league..
Luck
Cutler
LeVeon Bell
Lacy
Jennings
Fred Jackson
Sproles
McFadden
I am being offered Jamaal Charles and Stafford for..
Luck and Lacy.
So, I get a huge upgrade in RB but a downgrade in QB
I COULD take Russel Wilson instead of Stafford.
Charles has been nicked up a bunch this year. i'd stand pat
And Luck is money, week in and week out. You can depend on him for 20 to 30+ points a game (but I don't have to tell you that). Charles can be explosive, but he is a bit on the fragile side.
p.s.-- If you get 6 points for a TD pass, I definitely wouldn't make that trade.
