Won the startup year, sit tight or make small moves?

First year of this dynasty league. Most others are experienced Dynasty players and about half of the leaguemates in my team 2 are also from my league 1. Hit on Gurley in the 2nd round of the startup along with Kamara in the 9th and rode that muscle to multiple high scores of the week despite not having much depth (kendall wright was often the WR3 or 4, RB 3 was D Henry even when Murray was starting).

Any time a bye week came or small injury it became very apparent I didn't have the number of starters you'd like to have for a two flex league

QB is Wilson with Smith as backup
RB is Gurley, Kamara, D Henry (if Murray hopefully leaves)
WRs are M Evans, Diggs, Arob will be back and help a lot, and then Woods or Mike Williams if he ever gets healthy
TEs as Doyle and Hooper
notable other bench are Riddick, P Barber, and Allen Hurns. I believe Wright will go back to being the WR3 for the bears so not much use there

I do have my own first (1.12) and then the 2.10 and 2.12 to maybe just grab some rookie depth and hope for the best since I don't need them to truly hit as studs just useable guys. This league for whatever reason has definitely been more difficult to trade in than my league 1 where I feel half the teams don't have more than 2 players that were on their start of the season roster
