I'd say "solid" options for Thuney replacement is a risky assumption. Maybe at LG, but then that leaves an even BIGGER hole at LT if you move Kingsley inside. You aren't just replacing Thuney for LG, you are taking away either an All Pro LG or a serviceable LT when he was shifted outside. The Chiefs drafted Kingsley to be LT, and now they need to shift him in to be a serviceable guard, while leaving the hole at LT. It's a bit similar to the Cody Ford situation the Bills went through.
Hicks I'm solid on, but Reid was a big big player especially in the playoffs.
I severely doubt Hollywood is back. Severely. Chiefs need to add 2 solid WRs to their team, and this is a poor draft class to address it (Bills are in the same situation).
I think Bolton tests the market, and may come back depending on the offers.
I wonder if the org was really "happy" with Kelce coming back. He has obviously lost a step, and they could have saved I think $17M if he retired. Would've helped them fill some of these holes, and they could've drafted a TE to develop in a prime role (not saying that cant anyway, but now you have a chunk of cap AND a draft pick at the TE position.
