What do I do with my QBs?

I am in a 2 QB league, I drafted Kyler Murry, Jameis Winston and Trey Lance at the end of the draft. A couple weeks ago I picked up Taylor Heinicke so I didn’t have to play Winston against the Pats. I didn’t plan on keeping Heinicke but he keeps balling out. With Lance do I try to trade Heinicke?
