Depends on what you’re looking for. IMO Murphy is far superior as an inside rusher but Sweat is better overall as strictly a run defender. Murphy is pretty good there, he’s just not a guy who can hold up consistently in the run game. But I’d argue that neither can BJ Hill.
Re Outland, like a lot of those awards, it’s a popularity contest. Not saying Sweat didn’t deserve recognition, but Alex Leatherwood won it, too. Michael Oluwatimi last year. So it doesn’t mean much.
If the Bengals want a run stuffer, then yeah, first round is not the place to find it. But looking at the roster, the DT cupboard is pretty bare everywhere, and BJ Hill is on the last year of his deal. Further, DT generally is a weak class this year, whereas supposedly you can still find good OL after the first round. So while I’d prefer a move to protect the franchise and grab an OL, I wouldn’t be shocked if they took Murphy at 18 if he’s there… or failing that, if they love Johnny Newton, maybe a trade back and get another (or a better) pick in round 2 or 3.
