It would be helpful to know your league roster settings. Lineup, bench slots, how many keepers, etc.
Without that information, all I can say is:
QB looks very weak for a superflex league. Tua is a QB2, the rest looks much worse. As soon as Jimmy G gets benched, you’ll need to start a RB/WR on SFLEX, and you don’t have a bye week replacement for Tua. You definitely need to spend one of your 2022 1st round picks on a QB. Maybe even 2, if Jordan Love shouldn’t get the nod in Green Bay next year.
RB looks okay. Taylor and Harris are starters, Sermon should be one by the end of the season. You’re lacking a top tier talent here, but these are extremely hard to get in dynasty, if you don’t have a top 3 pick.
WR looks okay as well. McLaurin and Higgins are the starters here. Waddle should be another one sooner rather than later, do not trade him away. Smith-Schuster and Davis are WR3s. JuJu with more upside, Davis with the safer floor. Both can be traded away if the price is right.
5 TEs? Okay, your league obviously has very deep rosters, but still… 5TEs? Thomas is my favorite here. Don’t get too excited about the Gronk show from last night. There will be more episodes this season, but there will also be plenty of 2/20/0 games. If you have any owner who is ready to to pay a penny for Engram, sell him. If not, drop him. Everett and Albert O are keepers, though Albert is highly speculative.
Improving your roster via the waiver wire is probably not an option in a league with such deep rosters.
Overall, I can say that your roster is lacking top tier options on all positions. None of your players is a difference maker. Even if you need to start a lot of players and need the depth, you should have top tier players on at least 1 or 2 positions. When you build your depth, go for speculative upside players rather than backup pieces like Justin Jackson or James Washington, who offer virtually zero long term appeal.
