I think your RB core is fine. This is not dynasty so for this year I think you’ll be okay. I do like Roundtree / Ahmed but I’m not sure I’d swap any of your current RB, so unless you have bench guys not shown I’d hold.
TE you might be able to do something, but IMHO unless you are getting a top 3/4 TE they are all a wash, and you have two players who have history being good and on teams that keep TE involved. I suppose NEP is a history bias, but Bill is still there so it feels likely given their off-season moves. CLE will be running, but I think TE factors in.
From what you’ve shared, I’d be okay packaging Bateman / Ruggs to try and get a better option at RB or TE, but I’m not sure who you’d get. Maybe Carson if the owner doesn’t love him? I like Mike Davis for this year, and maybe Gaskin is out there. Then I’d grab a WR off the waiver to fill the depth there. WR is easier to find some potential production.
Unless you can get a good back end RB2 / high end RB3 I’d just ride out the year. I’m not sure how competitive you’ll be (IDNK league rosters), but your team is not “sexy.” Remember teams do not have to be sexy to win.
I hope any of this helps!
@Mr_Wind-up_Bird has a strong suggestion in dropping your K to add a player until the season starts.
