I think age will hurt them more than anything. A good chunk of their best talent is on the wrong side of their prime. Specifically, Thuney, Kelce, and Jones. They have some young talents on D that'll be nice and some solid WRs, but no one seems will have the same impact as those 3 yet. Luckily, Thuney and Jones are still monsters, but it can be any year that we start to see a decline... Kelce is clearly done and I expect Thuney is next.
Besides that though, their cap will be rough to fill all the holes. If they do keep Trey, they'll probably have to fill all those other roster spots with a bunch of free agent leftovers. I do think they'll keep Bolton too cause I've heard multiple times that Spags likes him and he was a captain as well. If that all happens, they'll be on the edge with injuries.
