Multi Trade help!

My team is scoring in the bottom 4 every week. I need advice on this. Trying to get QBs bc mine are injured benched or underperforming.

2 QB league with 6 point passing tds

I give up Kelce, Cousins, and Keenum for:
Mariotta, Jameis, and will Dissly.

I have Goff, so this will give me 3 useable QBS. I hate to lose Kelce but I have to make a change.
