Slight disagreement with your list.
First, no way they cut Hill. He'll make the 53 and might even start opposite TruJ with Gaines out for a couple of weeks.
I agree about Quick. The guy just isn't an NFL level WR; besides he also doesn't play STs. If he's not a starter, he has to play STs and he doesn't.
Green, yeah, cut and resign if he can get through waivers. Like him a lot.
I doubt they cut Forrest unless they are very impressed with someone else. Honestly haven't paid any attention to the back up LBs. Yeah, prolly 6 LBs due to STs. He was a draft pick.
If they keep Quick, I suspect it will only be because Spruce isn't fully healed. If Spruce is healed, I think Quick is gone.
