Dynasty Trade Help 12 team half ppr

This is my first year doing a dynasty league and I’m looking for some advice. 12 team half point PPR with a 20 man bench (start 10 QB, 2HB, 3WR, TE, K, D/ST) keep 25. I approached the draft without the “win now” mentality and ended up with 22/30 of my players as either 1st or 2nd year players and not a single player over the age of 27. My team is listed below. I have a chance to acquire Jamaal Williams to double down on the Packers RBs (I am an Aaron Jones guy but want to make sure in case Williams makes the leap) as well as Anthony Miller and Dede Westbrook for Nick Chubb, Mack Hollins, and Rico Gathers. Any thoughts would be appreciated!
