Trade 1 is a wash so without seeing ur roster its hard to say. As for deal 2.......i would prob take it just because I HATE the playoff schedule that Charles has, making him all but usless just when you need him most.
ROSTER/10 team QB-P.Manning/A.Luck RB-McCoy/T.Richardson/Mathews/D.Richardson WR-AJ Green/V.Cruz/D.Thomas/T.Smith/J.Gordon FLEX- RB/WR TE-H.Miller/M.Bennet
I would need to see your roster for the first trade because I don't know if you're weaker or stronger at rb or wr but I think Bryant has a breakout year this season.
Trade #2 I would actually keep Charles he averaged 6.4 ypc last year, the only thing that kind of held him back was Haley not giving him enough touches that's the one thing that concerns me. As much as I like Foster if his hamstring injury nags him throughout the season he's not going to have the same explosiveness he did last year at the same time I can see why you would make that trade.
