Dynasty trade MG3 vs Bell

Their mg3 and Michael gallup for my Lev bell.

I know bell seems like a turd based on news, but he will still be on the field almost all game. Melvin gordon makes me nervous with lindsay still lingering in the backfield. Am I insane not to just take it and run with the bonus of gallup?

My rbs are weak with David johnson, rojo, gibson, and jordan howard, so I need someone I can plug in consistently.
