Trades to be targeting

I’m in a standard leauge and I’m wondering if I should roll into the season with this team or should I target anyone/position to get a better tier player. My team is : Brees. Gurley, Howard, Michael Thomas, Doug Baldwin, trey Burton and flex Amari Cooper

Bench: L. Murray, b. Powell, r. Anderson, evan engram.

Was thinking to trade Howard and Amari for hunt or a better tier RB, any thoughts on who I should go after and what positions I should look to upgrade?
