Trading bell?

A team is inquiring about getting bell from me, I need a QB and he is willing to give up Brady or Dak with a piece to make that deal happen. what doing you guys think? [my league is set up that you need to play 10 off players a week, minimum 1 of each position but after that it doesnt matter who you put in so getting a RB back isnt as big of a deal as it usual would be] and would still ahve Hyde and shady on my team

Other players on his team are

Gordon, Howard, McKinnon, C.Thompson

Fitz, Garcon, TY, Hogan, Alshon, julio, Thielen, marvin jones
