If Ed Oliver fell to #10 (Denver). or #11 (Cincy), I would trade next years #1 to move up.
He's the one player that could make the Rams D-line unblockable. IMO, he is the closest thing to Aaron Donald to come out in the last couple of drafts. He is not at the top of everyone's board because his lack of sack production. And, if you look at how he was utilized at Houston the past 2 seasons, you would see that he plays more snaps at the true Nose position, "0" than any other D-tackle in the FCS. He played almost 550 snaps in 3 seasons at the NT position. Which was almost double the amount of snaps he took at any other position on the D-line. Even at 280lbs, PFF had him as one of the highest overall ranked DT's this past season, even considering his lack of sacks. If the Rams were to play him opposite of Donald, with Brockers in the middle, Oliver would not face double teams like he did playing NT at Houston. He would most likely be sole responsibility of the RightGuard and I like Oliver's chances of winning most of those battles.
Considering the Rams have been using high draft capital to trade for other players that are A) not being signed to extensions or B) paying them more than they're worth (see Brandin Cooks), They would have a player that would make an immediate impact and not be a burden to the Salary Cap.
