Jaray Bledsoe and Sydir Mitchell have gotten great reports and can fill the roles left by Murphy and Sweat respectively. Vernon Broughton has looked light years better this season and will still be around. That's also a testament to the job coach Bo is doing in developing guys, which means there may be some solid pieces we don't know about yet. Aaron Bryant may be a pleasant surprise.
It's also possible that some of the guys you listed will come back. Sweat is gone, but there has been talk about money-whipping Murphy into staying. Collins has indicated he wants to leave, which is stupid, but whatever. I'm not sure the light was ever going to turn on for him. Trill Carter walked on senior day, but otherwise there is no indication that he's decided to leave. He won't get a high draft grade and seems more likely to go UDFA, which means the staff can probably convince him to stay if they think he's worth the $$$.
Finally, most of the 2024 DL are early enrollees. That doesn't mean they'll be ready to start next season, but a few may be ready to contribute.
The DL room will be thinner, and we may not have a star like Sweat, but it won't be in bad shape either.
