Seems like draft position is a great indicator on this. Because the Rams generally have an accurate board, so if they take a guy like say Bruss at 104 there's a good chance he's vetted by many teams in that range when he came out. Also when a guy doesn't work out with a given team they're probably looked at in terms of their measurables, which insinuates that draft process factors in heavily.
So translation is if you cut Bruss he probably has a higher chance of being picked up than Thomas due to the gap in where they were taken. Teams I would assume will look at the film and think "well he had an injury setback" but bounced back. So if we cut Bruss I expect he'll get claimed. But a guy like Arcuri who IIRC was a UDFA probably clears waivers. Thomas probably has a reasonable chance to be claimed, as even though he was taken later teams do look for depth cuts like him this time of year on OL.
I wonder if you're overweighting draft position years ago to youth now. I'd argue that a player that a team evaluated this last year has more interest in them then one years ago (whose only recent tape is last two preseasons - one of those being pretty bad).
If we add in the dynamic factors of him being drafted for outside zone which many teams are moving away from and lack of production over many years, I don't see him getting picked up. But stranger things have happened. I don't think it's a great loss if we lose him.
Can't imagine Thomas get's grabbed either but could happen.
I wonder what the breakdown of positions are where players are picked up by other teams via cut down, if there's a pattern there. I could see OL being a spot where more pickups happen for sure.
Edit: I think everything I've been saying about Thomas and Bruss over the last few days comes with an overarching thought too, I don't think either is such a talent at backup that losing them is that big a deal especially with our depth at tackle and Noteboom being the swing guard/tackle. That being said, I think Thomas seems to be the more consistent of the two and offers more position flex. Hell, let's flip Bruss to LG and see if he could give a showing next game!
Oh, and ST value may make half of what I say about backup guards mute.
