Yes, several positions of need.
Agree with you: Rams also need defensive backs (especially a really good corner). Also on the shopping list; pass rusher and probably OL.
But ALSO -- WR. No way do Rams not bring in at least one really high draft pick at WR or big payday FA at WR. Heck, Kupp dropped two last night and he
is just a step slower and getting injured all the time. He was great. Time moves on. Tutu is "okay" at best. Robinson is a great find this year and maybe even a starting 3. Prediction: Puka and WR yet to be acquired will be the bases of a great one-two WR punch next year.
