I would trade Ingram to get Stafford.
10 team league; standard scoring; 1 QB, 2 RB, 2 WR, 1 TE, 2 Flex, 1 D/ST, 1 K. Below is my assumed starting lineup if I make the playoffs (big if right now because I basically need to win out). Also, things can obviously change if Jackson gets healthy and dominates or Peterson gets activated.
QB Colin Kaepernick
RB Rashad Jennings
RB Lamar Miller
WR AJ Green
WR Dez Bryant
TE Dwayne Allen
Flex Ronnie Hillman
Flex Mark Ingram
K Cody Parkey
DEF Houston
BN Tony Romo
BN Adrian Peterson
BN Fred Jackson
BN Jerick McKinnon
BN Kelvin Benjamin
BN Pierre Garcon
BN Zach Ertz
So I sent a message to a guy who had Brady and Stafford that I needed QB help because Kaepernick and the 49ers O-line looked horrible. He said he was only interested in Ingram but then I saw Romo had been dropped so I picked him up immediately. I told him we could discuss it after week 10 was over but I definitely don't think it should be straight up if I do it at all. He's strong at WR with Maclin, Nelson, Wallace, Boldin, and Smith Sr. but fairly week at RB with Lynch/Vereen and nobody else. Should I even consider doing anything?
