That would be my guess as well. Jones showed well as a rookie.I strongly suspect that they liked what they saw from Jones. His % of snaps was 37%, which was much higher than any of the other reserve safeties. They were willing to give him a lot of time on the field and do it during a playoff run. The other Safeties all had counts under 5%. He was THE guy.
I will be a little surprised if he doesn't take a run at one of the starters THIS year. He may not win the job outright, but he's going to make the two vets sweat.
On the WRs: I'm betting that they don't see the core as being as bad as most of our Alabama and KC Chiefs obsessed fans do. The front office micro-focused on a deep threat because they knew Grant can't catch a cold, and let the other FAs go without making an offer. ...and I'm further willing to bet that they are a LOT more forgiving of Preston Williams injury as it was pretty clear that it was caused by Christian Wilkins and a freak situation.
My one question is what do they think of Wilson and Bowden?
Looking at the wide receiver room, if Parker, Williams and Fuller are healthy, that's a good trio. The slot guys are a work in progress (Bowden, Perry), or in the case of Wilson kind of unknow injury-wise. That IMO is the biggest wide receiver hole for 2021. Long-term, you'd like to get a true #1.
