I always thought the Browns wanted the RDE to be a bigger, edge-setting guy to stymie the run. That doesn't describe Carter.
Half the planet thinks Hunter is a WR and half thinks he's a CB. Our history hasn't been good when we get these guys and don't know (definitively) where they should play. I don't think he is the best WR nor the best CB in this draft...an amazing talent for sure.
I'd rather take Dart (even if that's 8-10 spots too "early"). At least we know what position he plays and what role he fills.
I've always thought this iteration of the FO is more focused on pass rushing both on the exterior AND interior of the line. That's not to say that player couldn't have some impact on the run as well, but that the focus was getting to the QB and disrupting timing, etc. However, one of the bigger concerns about Carter is his power. Yes, he has the speed and bend but does he have the bull rush "ooompf" so to speak to over power a lineman. I think that some draft analysts peg him as a better fit as an OLB edge rusher in a 3-4 base...similar to guys his size and weight like TJ Watt or Micah Parsons.
