Honestly, I’m not so sure that Beane has actually hit on any stars - Cook might get there - other than Allen. The only other players from the McBeane era that hit a star level were drafted before Beane got here - Tre White, Dawkins, Milano. Aside from Cook, the only guys Beane has drafted that look like they could potentially be top 5 at their position are Spencer Brown, Torrence, and Groot… and Groot looks like he’ll never be a top pass rusher without help on the D-line despite being a dominant run defender at his position.
This team needs a dominant 1-tech like Dexter Lawrence or a dominant LDE like Garret, Hendrickson, etc to get guys like Oliver and Groot the 1 v 1’s they can reliably win. I agree that it’s worth some serious investment in cap and or draft capital to make that happen. As long as Allen is healthy this team isn’t going to draft in the top 20, so it’s trade, FA, or a red flag draft gamble to procure the physical talent needed there.
