I don't think the QB is as much of a problem as weakness at QB and
TE. Eifert obviously could come on as a stud but it's a risky proposition waiting that late on two positions in my opinion. You did land on some solid value at RB and WR though, and your top 3 at both positions is strong. If you only start 2 RBs a week you could look at downgrading RB3 a bit (as your top 2 are strong) to upgrade at QB.
Overall, decent team. I would explore the trade market at QB but don't force yourself to make a bad trade early. Perhaps look for some early buy lows on a QB or sell highs on one of your RBs/WRs.
Good luck this season
